Safety Messages
Safety Messages to Installers and Users of Warning Light Equipment
People’s lives depend on your proper installation and operation of Federal Signal
products. It is important to read and follow all instructions shipped with this
product and the original product. Listed below are some other important safety
instructions and precautions you should follow:
• To properly install this light, you must have a good understanding of
automotive electrical procedures and systems, along with proficiency in the
installation and service of safety warning equipment. Always refer to the
vehicle’s service manuals when installing equipment on a vehicle.
• DO NOT install equipment or route wiring in the deployment path of an airbag.
• When drilling into a vehicle structure, ensure that both sides of the surface are
clear of anything that could be damaged.
• For the light to function properly, a separate ground connection must be
made. If practical, it should be connected to the negative battery terminal.
At a minimum, it may be attached to a solid metal body or chassis part that
provides an eective ground path.
• Locate the light control so the VEHICLE and CONTROL can be operated safely
under all driving conditions.
• The eectiveness of an interior mounted warning light depends on the clarity,
the tinting, and the angle of the glass it is placed behind. Tinting, dirt, defects,
and steeply angled glass reduce the light output of the warning light. This may
reduce the eectiveness of the light as a warning signal. If your vehicle has dirty,
tinted, or steeply angles glass, use extra caution when driving your vehicle or
blocking the right of way with your vehicle.
• Do not attempt to activate or deactivate the light control while driving in a
hazardous situation.
• Frequently inspect the light to ensure that it is operating properly and that it is
securely attached to the vehicle.
• This product contains high-intensity LED devices. To prevent eye damage, DO
NOT stare into the light beam at close range.
• After installation, test the lights to ensure that they are operating properly.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if
the seat needs to be recalibrated for proper airbag deployment.

Product Overview
The SpectraLux®XStream®LED Series light heads are low-current warning lights
that are mounted only on the inside of the vehicle. The light head uses Solaris®
LED reflector technology to provide a bright and eective secondary warning
signal. XStream models have 18 LEDs per head that can be ordered in various
color combinations with a clear lens. Wire lead (Sync) and accessory plug models
are available.
All XStream models are designed for use with all Federal Signal switch controllers.
The XStream is supplied with hardware for mounting the light head horizontally
on the vehicle deck or dash. Additional bracket kits are available. The light heads
have an operating temperature of –30º C to +65º C (–22º F to +149º F).

Installing the Light Heads
AIRBAG DEPLOYMENT: Do not install equipment or route wiring in the
deployment path of an airbag. Failure to observe this warning will reduce the
effectiveness of the airbag or potentially dislodge the equipment, causing
serious injury or death.
LIGHT OUTPUT COMPLIANCE: This product is intended for supplemental
warning in conjunction with an approved primary warning light system.
Consult local codes and regulations to determine if the power supply/light
head combination complies with the horizontal or vertical mount position
required in your application. Failure to follow this warning could result in
reducing the light output and its effectiveness as a warning system.
LIGHT HAZARD: To be an effective warning device, this product produces
bright light that can be hazardous to your eyesight when viewed at a close
range. Do not stare directly into this lighting product at a close range, or
permanent damage to your eyesight may occur.
Before installing the lights, read all instructions and plan all wiring and cable
routing. To secure and protect the wiring, use grommets, wire ties, looms, and
cable mounts (installer-supplied) as needed.

the applicable mounting method.
Mounting the Light with Suction Cups
SUCTION CUPS ARE FOR TEMPORARY USE ONLY: Suction cup mounting
is for temporary applications only. This unit should be removed from the
vehicle and stored securely when not in use. Temperature changes and
sunlight can cause suction cups to lose holding power. Periodically check
the unit to ensure that the suction cups have a rm grip on the mounting
surface. An improperly secured light could fall off the windshield, causing
injury and damage.
To mount the light with suction cups:
1. Attach the appropriate visor to the light head. Press the visor firmly until it
snaps into place. See Figure 1 on page 4.
2. Attach the suction cups to the bracket.
3. Attach the pivot bracket to the light head using the supplied #8 pan-head
screws. Do not overtighten.
4. Attach the bail bracket to the pivot bracket with the supplied #10 pan-head
screws and lockwashers. The lockwashers go between the bail and the pivot
bracket.
5. Apply the suction cups to the glass.

Installation and Service Instructions

USE THE DIMMING/LOW POWER FUNCTION PROPERLY: Enabling the
Low Power function in the light bar may cause the light output to fall below
certain light output standards and guidelines for emergency warning lights.
Use extreme caution when using this function. Ensure that the ambient
light conditions are low enough that you are seen and that the reduction of
glare from the light bar is safer than full light output in the situation. Failure
to heed this warning may result in serious injury or death to you or others
in your vicinity.
