T-REXTM Series Exterior Lights
WARNING: This product contains high intensity LED devices. To prevent eye damage, DO NOT stare into the light
beam at close range.
WARNING: The use of this or any warning device does not ensure that all drivers can or will observe or react to an
emergency warning signal. Never take the right-of-way for granted. It is your responsibility to be sure you can pro-
ceed safely before entering an intersection, driving against trafc, responding at a high rate of speed, or walking on or
around trafc lanes. The effectiveness of this warning device is highly dependent upon correct mounting and wiring.
Read and follow the manufacturer’s instructions before installing or using this device. The vehicle operator should
insure daily that all features of the device operate correctly. In use, the vehicle operator should insure the projection of
the warning signal is not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or
other obstructions. This equipment is intended for use by authorized personnel only. It is the user’s responsibility to
understand and obey all laws regarding emergency warning devices. The user should check all applicable city, state
and federal laws and regulations. Code 3, Inc., assumes no liability for any loss resulting from the use of this warning
device. Proper installation is vital to the performance of this warning device and the safe operation of the emergency vehicle. It is important to recognize that the operator of the emergency vehicle is under psychological and physiological
stress caused by the emergency situation. The warning device should be installed in such a manner as to: A) Not reduce
the output performance of the system, B) Place the controls within convenient reach of the operator so that he can operate the system without losing eye contact with the roadway. Emergency warning devices often require high electrical
voltages and/or currents. Properly protect and use caution around live electrical connections. Grounding or shorting
of electrical connections can cause high current arcing, which can cause personal injury and/or severe vehicle dam-
age, including re. PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.
INSTALLER: This manual must be delivered to the end user of this equipment.
Introduction: Read all instructions and warnings before installing and using. The T-RexTM Lights are for the emer-
gency vehicle market. The lights are to be connected directly to +12 VDC systems for independent ashing or through
electromechanical or solid state asher units.
Unpacking & Pre-Installation: Carefully remove the hardware, taking care not to scratch the lens, and inspect for
transit damage. Report any damage to the carrier and keep the shipping carton. Verify the contents of the package
(refer to Table 1 and Figure 1). Test the lights before installation. To test, touch the black wire to the ground and the red
wire to 12 VDC. If problems occur, contact the factory.
Installation & Mounting
1. Mark off and drill two mounting holes (#32) and the 1” wire hole on the vehicles mounting surface using the dimensions shown on Fig 2. Verify free clearance exists behind the mounting surface for wires and fasteners before drilling.
2. Install customer supplied grommet in the 1” diameter wire hole.
3. Route the vehicle power wires and allow a minimum of 3” of slack to protrude from the center opening at each light
head location. Use 18 AWG for wires up to 40’ length, 16 AWG for wires up to 70’ length.
4. Refer to the section “Flash Pattern Selection” prior to nalizing the electrical connections. Prepare the vehicle power
wires and the light heads wires with terminations of the customer’s choice (not supplied) as follows: Red: +12 VDC,
Black: Ground, White: Program, Purple or Blue: Sync. Waterproof connectors are recommended.
5. Route the power wires through the center opening of the bezel gasket (refer to Figure 1). Connect the light heads
power wires (black and red) to the vehicle system’s ground and positive (+12 VDC), respectively. Seal or cap the end
of the white wire to prevent inadvertent changes to the ash pattern. To sync light heads, connect the purple wires
together.

6. Verify proper light head operation by supplying electrical power to the system wires.
7. Push the assembled electrical connectors through the center opening and into the vehicle.
8. Secure the assembled light head to the vehicle using the two #6 screws. To ensure the unit is properly installed and
seals properly seated, torque the screws as follows: 6 in-lbs to 13 in-lbs.
