VERTICAL FIN
One anti-collision strobe light
mounted on the vertical fin will
meet the minimum require-
ments on most aircraft. A half
red and half white lens is re-
commended.
WINGTIP
Two wingtip strobe lights that
protrude beyond the wingtip,
their light converging in front
and back of the aircraft within
1200 ft. is an approved anti-
collision strobe light system.
ENCLOSED WINGTIP
Enclosed wingtip anti-collision
strobe lights, require a third
strobe light on the tail or verti-
cal fin, to fill in the required
light envelope. This is an
approved anti-collision sys-
tem.
FUSELAGE
In a fuselage mounted anti-
collision strobe light system, a
minimum of two strobe lights
are necessary to get the
required vertical coverage.
This is an approved anti-colli-
sion system.
An approved anti-collision
strobe light system must proj-
ect light 360° around the air-
craft’s vertical axis. One or
morestrobelightscanbeused.
An approved anti-collision
strobe light system must proj-
ect light + or - 30° above and
below the horizontal plane of
the aircraft. One or more strobe
lights can be used. The + or -
75° projected light is required
since July 18, 1977.
Approved light pattern in
the horizontal plane.
The anti-collision
wingtip mounted lights
must converge within
1200 feet directly in
front and rear of the
aircraft on center line.
If the wingtip strobe
light convergence is
greater than 1200 ft. in
back of the aircraft,
a 3rd light is necessary.
POSITION LIGHTS AND ANTI-COLLISION LIGHT
DISTRIBUTION PATTERNS REQUIREMENTS
INTRODUCTION TO WHELEN ANTI-COLLISION STROBE LIGHTING
SYSTEMS, STC SA800EA/STC SA615EA/STC SA6NE/
STC SA21NE
Whelen’s Anti-Collision Strobe Light Systems are approved under STC
SA615EA, STC SA800EA, STC SA6NE, and STC SA21NE, manufactured under
PMA as an approved anti-collision light for all aircraft, when installation is
accomplished in accordance with the following instructions.
Whelen’s Anti-Collision Strobe Light Systems are designed and approved spe-
cifically for General Aviation Aircraft, to comply to FAR 91.205(c) (3) (visual
flight rule night) requirements.
Whelen’s approved Anti-Collision Strobe Light Systems can be installed on all
aircraft by completing the installation with reference to this Installation and
Service Manual, and the appropriate technical data listed below:
ADVISORY CIRCULAR 43.13-1A, Chapter 11, Sections 1, 2, 3 and 7,
Electrical Systems.
ADVISORY CIRCULAR 43.13-2A, Chapters 1 and 2, Radio Installations.
ADVISORY CIRCULAR 43.13-2A, Chapter 4, Anti-Collision Light Installations.
ADVISORY CIRCULAR 20.21, 12-3-64, Application of Glass Fiber
Laminates in Aircraft.
ANTI-COLLISION AND POSITION LIGHT REQUIREMENTS,
LOCATIONS, & DISTRIBUTION PATTERNS
All aircraft must have an approved anti-collision light and position light system
for nighttime operations. The position lights consist of an Aviation Red on the
left side, an Aviation Green on the right, and an Aviation White taillight (REF. FAR
23.1389).
The anti-collision lighting system is required under FAR PART 91.205(c)(3).
There are different requirements affecting different aircraft. These aircraft are
categorized by the date of application for type certificate. Home built aircraft are
determined by the date of issuance of the Experimental Operating Limitations.
The different categories are as follows:
Aircraft for which type certificate was applied for after April 1, 1957 to
August 10, 1971:
These anti-collision systems must produce a minimum of 100 effective candela
in Aviation Red or White (REF. FAR 23.1397), 360º around the aircraft’s vertical
axis, 30º above and below the horizontal plane (REF. FAR 23.1401).
Aircraft for which type certificate was applied for after August 11, 1971 to
July 18, 1977:
These anti-collision systems must produce a minimum of 400 effective candela
in Aviation Red or White (REF. FAR 23.1397), 360º around the aircraft’s vertical
axis, 30º above and below the horizontal plane (REF. FAR 23.1401).
Aircraft for which type certificate was applied for after July 18, 1977:
These anti-collision systems must produce a minimum of 400 effective candela
in Aviation Red or White (REF. FAR 23.1397), 360º around the aircraft’s vertical
axis, 75º above and below the horizontal plane (REF. FAR 23.1401).
*The position lights must be wired independently of anti-collision lights.
GENERAL AVIATION MINIMUM POSITION LIGHTING
REQUIREMENTS
For compliance to FAR Part 23.1385 through 23.1397, VFR flight rule night
requirements on a General Aviation aircraft, you must have a TSO'd Aviation Red
forward position light on the left and an Aviation Green forward position light on
the right. See Figure 7, page 4.
These are normally mounted on the most outward extremity of the airframe so
they can project their light directly in front of the aircraft 0 degree to 110
degrees left and right horizontally, and 180 degrees up and down vertically,
unobstructed by any part of the aircraft.
The tail position light must project its Aviation White light toward the rear of the
aircraft, 70 degrees horizontally left and right from 0 degree straight back
behind the aircraft, 180 degrees up and down, 0.04 Steradian (131.36 sq.
degrees) interference is allowable, reference FAR Part 23.1387(c). More than
one light is acceptable.

ANTI-COLLISION LIGHT INSTALLATION PROCEDURES
STC SA800EA / STC SA615EA / STC SA21NE
The following information is to assist in the installation of a custom
Whelen anti-collision strobe light system on any aircraft, and how to
return the aircraft back to service with compliance to FAR Part
91.205(c) (3).
1.Choose the anti-collision light system which is most applicable to
the aircraft.
2.With reference to the STC’s “Limitation and Conditions” for field of
coverage requirements. Check the field of coverage of the pro-
posed location.
3.These STC’s document that Whelen’s anti-collision strobe lights
meet the requirements as specified in AC 43.13-2A, Chapter 4,
PAR.51 (a and b) (1). STC SA615EA covers replacement of original
equipment, STC SA800EA and STC SA21NE cover installation of
new anti-collision light systems.
4.Vertical fin mounted anti-collision strobe beacons will conform to
the FAR 23.1401, 0.5 steradian (1642 sq. degrees) maximum solid
angle blockage requirements on most standard configurations
(CAM 3 and FAR Part 23) high or low wing type aircraft. An aver-
age solid angle blockage for an installation of this type is 1324 sq.
degrees.
5.Fuselage mounted anti-collision light systems require two (2) anti-
collision strobe beacons to get the +/– 75 degrees required. Two
lights mounted in this manner exceed the steradian requirements
of 21,600 sq. degrees total coverage.
6.Fuselage mounted anti-collision lights should be located on the
fuselage center line to reduce reflection on the wings as much as
possible. They should be mounted near the trailing edge of the
wing, to reduce cockpit reflection.
APPROVED METHOD OF DETERMINING ADEQUATE
COVERAGE OF WING AND TAIL STROBE LIGHT
INSTALLATIONS
The most practical system is the approved wingtip anti-collision strobe
light system. These systems consist of two or more lights to complete
the anti-collision light requirement. There is no question as to their
complying to the field of coverage when the installation is completed
(Reference to the following instructions).
The acceptable distance for the two wingtip anti-collision strobe lights
to converge in front and back of the aircraft on center line is 1200 feet.
If both wingtip anti-collision strobe lights can be seen at 1200 feet or
less directly in front and back of the aircraft, it is considered a point of
light source, therefore a third light is not necessary.
The wingtip anti-collision light must be located in such a way that it will
project light +/– 75 degrees above and below the horizontal axis of the
aircraft, and the summation of the 2 or 3 lights will project light 360
degrees around the vertical axis.
PILOT AND CREW INTERFERENCE: In some installations it will be
necessary to mask the strobe lighthead assembly to reduce pilot
annoyance. This interference problem varies from one aircraft to
another of the same model, due to paint schemes and colors. The
Navigation Light Detector will be a source of reflection and should be
reduced in size, or masked as necessary. A small aluminum or plastic
plate mounted between the navigation light and the wingtip protruding
up or down as required (like some plastic navigation light detectors,
and trimmed to shadow the objectionable reflected area) is simple and
very effective.
The solid angle blockage must be reviewed after installing any masking
that will disturb the 360 degrees by +/– 75 degrees pattern. The afore-
mentioned type masking used on wingtip lighting seldom interferes
with this pattern.
ESTABLISHING SOLID ANGLE BLOCKAGE WITH REFERENCE TO AC
43.13-2A, CHAPTER 4.
1.To determine the vertical angles to use with reference to Figure 7
and 8 of the aforementioned chapter 4, attach a long string to the
subject light source location.
2.Fix a navigational-type plotter or protractor to the string with
weighted thread fixed to the center of the scale for a plumb bob.
3.Level the aircraft or determine the offset angle.
4.Pull the string over the point of solid angle blockage (Ref. Fig. 6
page 4). Any angles greater than +/– 75 degrees vertical are not a
factor.
5.Apply the vertical and horizontal angles to the graph paper (Ref.
Fig. 4.8 and instructions in text of paragraph b6 & c of Chapter 4).
A flight test will be performed by properly certified pilot with reference
to paragraph 52(a) (b) of Chapter 4.
COMPLETING THE ANTI-COLLISION LIGHT INSTALLATION
1.Check all avionics systems for interference from this installation,
reference AC 43.13-2A, Chapter 4, Paragraph 52(b).
2.A flight check will be performed by a properly certificated pilot with
reference to AC 43.13-2A, Paragraph 52(a) and (b).
3.If a solid angle blockage document must be established, it should
be performed after all masking has been installed and all flight test-
ing is completed. See page 3 of this manual.
4.WATERPROOFING OF STROBE LIGHT INSTALLATIONS: When
necessary to waterproof the installation of a strobe light mounting
to the aircraft, apply GE (silicone rubber) RTV 102 (or equivalent)
around the open area where water could get in.
5.Label all switches and breakers, install Pilot Warning Placard.
6.Up-date aircraft records and complete form 337.

INSTALLATION PROCEDURES:
Location
1. Consider areas or locations designated by the aircraft man-
ufacturer. Do not mount the strobe power supply closer than
three (3) feet of the ADF loop.
2. For alternate locations, consider areas such as the cabin
baggage compartment, the floor under the seat, nonstruc-
tural bulkheads, firewalls, etc.
3. If necessary, fabricate support brackets or shelves, and
attach them to the aircraft structure to provide a mounting
surface that will withstand the inertia forces stipulated in
chapters 1 & 3 of AC 43.13-2A.
4. An “IA” or other representative of the FAA must approve
documentation of structural integrity of the fabricated instal-
lation.
5. When installing the strobe light power supply in an inverted
position, drill a 3/16” diameter hole in the lowest corner of
the cover to provide for moisture drainage. Care must be
taken not to let the drill protrude into the power supply, for
it will inflict damage to the electronic components.
6. Specifically call out the location of the strobe light power
supply on FAA form 337.
Wiring
WARNING!!! STROBE LIGHT POWER SUPPLIES ARE
POLARITY SENSITIVE. REVERSING THE INPUT
POLARITY WILL CAUSE SEVERE DAMAGE TO THE
POWER SUPPLY!
Steps below: Ref. AC 43.13-1B, Chapter 11, Sections 1, 2, 3 & 7.
1. Choosing wire size of A+ input lead, refer to Paragraph 444
“Electric Wire Chart” Figure 11.7 & 11.7a, with reference to
“Strobe Light Model Current” requirement chart on page 6 &
11, and “Wire and Circuit Protection Chart” Figure 11.1.
2. Shielded wire is not generally necessary, but has proven
effective in reducing the possibility of radio interference.
3. The power supply shall acquire its power from a low imped-
ance source such as the alternator or generator end of the
electrical buss as close to the battery as possible. Do not
ground power supply to airframe. This can attenuate emi/rfi
noise to airframe causing it to act as an antennae for inter-
ference in aircraft audio & electrical systems.
4. For penetrating pressure hull, refer to the aircraft service
manual.
5. Check all avionics systems for interference.
Important Note
Your new strobe power supply has an additional circuit built-in
to prevent self-ionization (steady glowing) of the strobe tubes.
In some cases, when replacing older power supplies, the bare
shield wire in the existing harness is pinned together at each
end with the black wire. The following modification must be
made to ensure proper operation.
1. At the strobe tube end of the cable, cut the shield wire and
tape it off (DO NOT CUT THE BLACK WIRE).
2. At the power supply end of the cable, cut the shield wire and
connect it to a good ground (DO NOT CUT THE BLACK
WIRE).
3. This must be done for each strobe light connection (See
Figure 6a).

draw and provides thousands of hours of operation.
Operation
EQUIPMENT LIMITATIONS:
An approved position lighting system consists of three lights, one
located the tail and one on each wingtip. Model OR500( ) is a tail
position and anti-collision light. The assembly should be mounted as
far aft on the aircraft as practicable on a thermally conductive sur-
face.The baseplate must be mounted parallel to the vertical and
horizontal centerlines of the aircraft to project the patterns properly.
Certain types of installations may require additional testing.
CONTINUED AIRWORTHINESS:
The tail position light is designed with 4 LEDs. The anti-collision light
is designed with 18 LEDs. If any one LED fails, the unit must be
repaired or replaced.
Inspect the lens, replace if there is excessive scratching, pitting,
discoloration or cracking.
Note: To reduce eye strain, use an optical filter such as dark glasses
or a blue covering dome during LED inspection.
INSTALLATION PROCEDURES:
The following information is to assist you in installing a Whelen light
system.
1.Choose the appropriate light assembly.
2.Using the mounting detail information provided, prepare the
aircraft for means to secure the light assembly.
3.Connect the light inputs according to the chart shown. Connect
the power lead to an appropriate sized breaker. Connections to be
in accordance with FAA approved methods. Note: SYNC is a low-
power, bi-directional control signal. Connecting to the synchro-
nize signal of any Whelen LED anti-collision assembly to another
Whelen anti-collision assembly will cause the lights to flash at the
same time. If synchronization is not necessary, the connection
may be left open.
4.Proper installed orientation is achieved with the drain hole down.
Note: The arrow on the label must point up. Install the light
assembly on to the aircraft. Insure that all leads are clear of any
obstructions and secured as required.
5.When necessary, waterproof the light base to aircraft. Apply
single-part Silicone (RTV) or equivalent around any open area
where water could get in. Do not cover the drain hole or the back
of the unit.
6.Check all avionics systems for interference from this
installation.

ORION 650 LED LIGHT ASSEMBLIES
Operation
EQUIPMENT LIMITATIONS:
An approved forward position lighting system consists of three
lights, one located on the tail and one located on each wingtip. Model
OR650( ) is a wingtip forward position and anti-collision light.The
assembly should be mounted as far outboard on the aircraft as prac-
tical. The baseplate must be mounted parallel to the vertical and
horizontal centerlines of the aircraft to project the patterns properly.
Certain types of installations may require additional testing.
CONTINUED AIRWORTHINESS:
The forward position light is designed with Green or Red LEDs. The
anti-collision light is designed with 18 White LEDs. If any one LED
fails, the unit must be repaired or replaced.
Inspect the lens, replace if there is excessive scratching, pitting,
discoloration or cracking.
Note: To reduce eye strain, use an optical filter such as dark glasses
or a Blue covering dome during LED inspection.
INSTALLATION PROCEDURES:
The following information is to assist you in installing a Whelen light
system.
1.Choose the appropriate light assembly.
2.Using the mounting detail information provided, prepare the
aircraft for means to secure the light assembly.
3.Carefully remove the #4 phillips head screw and lens retainer.
Remove the lens from the light assembly by lifting the rear of the
lens approximately 1/2”. Now slide the lens rearward approxi-
mately 1/4” and lift upwards to remove. CAUTION! To avoid
potential damage, do not touch the LEDs with either fingers
or sharp objects. Remove the 3 Phillips head screws securing
the baseplate to the light assembly. Remove baseplate.
4.Using the appropriate hardware install the baseplate directly to
the aircraft.
5.Route the wires through the opening in the baseplate. Connect
the light inputs according to the chart shown. Connect the power
lead to an appropriately sized breaker. Connections to be accord-
ing to FAA approved methods. Note: SYNC is a low-power,
bi-directional control signal. Connecting to the synchronize
signal of any Whelen LED anticollision assembly to another
Whelen anti-collision assembly will cause the lights to flash at the
same time. If synchronization is not necessary, the
connection may be left open.
6.Re-install the light assembly on to the baseplate and
insure that all leads are clear of any obstructions and
secured as required. Note that proper orientation is
achieved with the drain hole down.
7.Install lens in the reverse order as removal and return
the lens retainer to its installed location. Note: Visually
confirm that the lens and retainer are fully and prop-
erly seated. Re-insert #4 phillips head screw and
tighten firmly.
8.When necessary, seal the light to the aircraft. Apply
sealant around the perimeter of the base. Do not cover
the drain hole.
9.Check all avionics systems for interference from this
installation.
10.A flight check should be performed by a properly certi-
fied pilot.
11.Update aircraft records, complete Form 337 and obtain
FAA field approval for installation, if required.

Operation
This power supply will operate up to 3 strobe lighthead assemblies.
When operating two lights in the alternating mode, 42 joules of power
are produced for each light. While in simultaneous mode, power to
each light is 21 joules. When operating 3 lights, strobe outlet 1 pro-
duces 42 joules of power and alternates with strobe outlets 2 & 3
(producing 21 joules each) that flash simultaneously (see Figure 13b).
Trigger Function
Jumping pins 1 and 2 on the trigger plug will provide an alternating
flash pattern between strobe outlet 1 and strobe outlet(s) 2 and/or 3.
Installing a switch in series with the jumper will allow strobe outlets 2
& 3 to be turned off, while strobe outlet 1 remains on (see Figure 13b).
