remote control. Each spotlight has 370° horizontal rotation and 135°
vertical tilt.
The RadioRay GT Includes:
•RadioRay® GT Spotlight
•Wireless Handheld Remote with two A23 12V Batteries
• Wireless Dash Remote (if applicable) with two A23 12V Batteries
and four mounting screws.
• Stainless Steel Mounting Plate and Black Rubber Mounting Gasket
• Mounting Hardware Package with four rounded head sheet metal screws and four flat head machine screws

MOUNTING INSTRUCTIONS - SPOTLIGHT
1. Determine the location for the light on your vehicle. This should be a
flat surface. The small arrow on the base indicates the normal forward
direction of the light. The light will rotate to the left of this arrow 185
degrees and to the right 185 degrees. The lamp will tilt down 45
degrees and tilt up 90 degrees. The location should take into
consideration this range of motion to maximize usability. Keep in mind
the swing diameter is 261.4 mm (10.3 inches) from the center of the
mounting plate – see Figure 1. This allows for clearance as the light is
rotating.

3. Drill a center hole in mounting surface for passage of power leads.
Minimum suggested diameter is 6 mm (1/4 inch).
4. Place the black mounting gasket under the mounting bracket and
attach the bracket and gasket to vehicle using preferred hardware.
Silicone or other like sealants should not be used around the
mounting gasket as it will limit the ability to drain water properly.

3. The wire leads under the light need to be connected to a fused 12V DC power source on the vehicle. It is critical that
polarity be observed. Connect vehicle positive (+) to spotlight positive (+) wire. Connect vehicle chassis ground (-) to
spotlight ground (-) wire. Use appropriate wire gauge and fuse for your light and appropriate automotive wiring
connectors. For best results wire the spotlight to a dedi-cated power source. As indicated in the reprogramming
procedure, removing and reapplying power to the light initi-ates a frequency code search phase for six seconds.
Wiring the light to dedicated power source eliminates unwanted frequency disturbances.
4. Electrical requirements are as follows:
Halogen Models
Max Current Draw: 5.5A @ 13.8V
Recommended Fuse: 7.5A to 10A
LED Models
Max Current Draw: 3.5A @ 13.8V
Recommended Fuse: 5A
7. Use silicone sealant to fill center hole around power cord. IMPORTANT: Allow 75 mm (3 inches) of cord to remain
under light to ensure full 370 degrees rotation.
8. Seat spotlight base onto mounting bracket. Use four flathead machine screws (included) to secure spotlight to
mounting bracket. Press rubber tabs on mounting gasket into plastic base.
9. Mechanical and electrical installation of the spotlight is now complete.
BATTERY INSTALLATION
WIRELESS HANDHELD REMOTE
1. Remove the battery compartment cover from the rear of the handheld remote
by removing the single rounded head screw.
2. Insert the two supplied 23A 12V batteries. Note batteries must be installed with
proper polarity (+ and - ) as shown inside battery compartment. See Figure 3.
3. Reinstall battery cover and screw.
REPROGRAMMING – WIRELESS HANDHELD REMOTE
The RadioRay handheld remote is pre-programmed to the spot-light using a
default setting at the factory. Golight recommends reprogramming the remote to
the spotlight to prevent cross-talk with other spotlights in your fleet or in your area.
Figure 3
Figure 3 - Wireless Handheld Remote
Reprogramming simply involves changing the DIP switch set-tings inside the
remote and the spotlight will re-learn the new channel. There are 2187 possible
channels.
1. Disconnect power to the spotlight.
2. Remove battery cover from the handheld remote.
3. Set the seven DIP switches (See Figure 3) to the selection of your choice using a small flat screwdriver. Note each
switch has positive and negative settings with neutral in the middle. Note the orientation of the positive and negative
settings may vary between the wireless handheld and wireless dash mount.
4. Replace battery cover.
5. Depress the on/off button and hold it down while reconnect-ing power to the spotlight.
6. Release the on/off button after 6 seconds.

BATTERY INSTALLATION AND MOUNTING
WIRELESS DASH REMOTE
1. Remove black rubber cover.
2. Mount the wireless dash remote to smooth flat surface with the four
supplied mounting screws. Note the arrow on the plastic base (near
LED) must be pointing up see Figure 4.
Figure 4
Figure 4 - Wireless Dash Remote
3. Insert the two supplied 23A 12V batteries. Note batteries must be
installed with proper polarity (positive and negative) as shown inside battery
holders.
4. If you chose to reprogram the wireless handheld remote then change the
DIP switch settings (positive, negative or neutral) in the wireless dash
remote to match. Checking the +/- designation on the DIP switches is the
only way to be certain they are programmed identically. Do not use ‘up/
down’ as a guide.
5. Reinstall rubber cover over plastic base. The tab on the cover needs to
be located at the bottom.
OPERATION OF GOLIGHT RADIORAY

SAFETY PRECAUTIONS
Your Golight RadioRay GT contains a radio transmitter and receiver operating at 433 MHz. Whenever the light is on, the
internally mounted antennas send out and receive radio frequency (RF) energy.
Modern electronic equipment, i.e. personal medical devices such as pacemakers, hearing aids, etc., are shielded from RF
energy. However, RF energy may affect some electronic equip-ment.
Vehicle electronic systems may be affected by RF energy. Check with your vehicle manufacturer representative to be sure
that your RadioRay GT will not affect the electronic system of your vehicle.

Quick Troubleshooting Guide Golight GT Series Halogen and LED Wireless Remotes
REMOTE TYPE: WIRELESS HANDHELD OR WIRELESS DASH MOUNT REMOTE CONTROL
1. My light has NO function. Potential issues:
•Insufficient Power Supply
•Programming Issue (Wireless Remotes Only)
•Defective batteries or Defective Wireless Remote
•Defective Receiver
Insufficient Power Supply- Verify your light is receiving adequate current. Halogen units draw 5.5 Amps at 13.8V / LED
units draw 3.7 Amps at 13.8V.
Programming Issue- See “Wireless Remote Programming” instructions listed under “Helpful Links” on the Product
Support page or refer to the white sticker on the back of your wireless remote control.
Defective Batteries or Defective Wireless Remote- There is a red LED light in the center of your wireless remote control
that should light up every time you depress a button. If there is no red LED light, start by replacing the batteries in your
remote control (12V 23AE). If this does not resolve the issue, the problem could be with the remote control. If available, use
a different remote control to test the light. If a different remote is not available, please call our Customer Service
Department for assistance.
Defective Receiver- If you have done all of the above and your light still has no function; you may have a defective
receiver. Please call our Customer Service Department for further instructions.
2. My light will rotate left/right and up/down, but the bulb will not illuminate. Potential issues:
•Insufficient Power Supply
•Polarity Reversed
•Defective Halogen Bulb
•Defective Receiver
Insufficient Power Supply- If the motors are operational, this is a sign that the unit is receiving adequate current, but not
enough current to illuminate the bulb. Verify your unit is receiving adequate current. Halogen units draw 5.5 Amps at
13.8V / LED units draw 3.7 Amps at 13.8V.
Polarity Reversed- Our LED units are polarity sensitive (Halogens are not). If your light will rotate, but not turn on, verify
your power wires are hooked up accordingly (+) to (+).
Defective Halogen Bulb- Is there a break in the filament? If no, remove the bulb and perform a continuity test.
Defective Receiver- When pressing the power button on the remote control, do you hear a “clicking” sound? If so, this
means the receiver and the remote control are communicating, and the issue is most likely the bulb. (Please note: in rare
circumstances, a defective receiver can still produce a clicking sound.) If you do not hear anything when you press the
power button, the issue could be the receiver.
3. My light will illuminate, but has rotation issues (no left/right, up/down, or both). Potential issues:
•Defective Motor
•Defective Receiver
•Defective Wireless Remote
Defective Motor- There are two motors in the light; One that controls horizontal movement and one that controls vertical
movement. If your light will turn on but will not move L/R or U/D, then you may have a defective motor.
Defective Receiver- If your light illuminates but rotates intermittently or not at all, your receiver may be the issue.
Defective Wireless Remote- There is a red LED light in the center of your wireless remote control that should light up
every time you depress a button. If it does not illuminate when depressing the left, right, up or down arrow you may have a
defective remote. If available, use a different wireless remote control to test the light. If a different remote is not available,
please call our Customer Service Department for assistance.
