FOR

MODEL GH1K GRILLE LIGHT KIT

SAFETY MESSAGE TO INSTALLERS AND USERS

People’s lives depend on your safe instal-

lation of our products. It is important to 

read, understand and follow all instruc-

tions shipped with the products. In addi-

tion, listed below are some other impor-

tant safety instructions and precautions 

you should follow:

•  To properly install a light assembly: 

you must have a good understanding 

of automotive electrical procedures 

and systems, along with proficiency 

in the installation and use of safety 

warning equipment.

•  DO NOT install equipment or route 

wiring in the deployment path of an 

air bag.

•  When drilling into a vehicle struc-

ture, be sure that both sides of the 

surface are clear of anything that 

could be damaged.

•  A light system is a high current de-

vice. In order for it to function prop-

erly, a separate ground connection 

must be made. It should be connected 

to the negative battery terminal.

•  Locate light system controls so the 

VEHICLE and CONTROLS can be 

operated safely under all driving con-

ditions.

 

•  You should frequently inspect the 

light to ensure that it is operating 

properly and that it is securely at-

tached to the vehicle.

•  File these instructions in a safe place 

and refer to them when maintaining 

and/or reinstalling the product.

 

Failure to follow all safety precautions and 

instructions may result in property damage, 

serious injury, or death to you or others.

This product is intended for supplemen-

tal warning and for use in conjunction 

with an approved primary warning light 

system. This strobe head can be powered 

by several types of strobe power sup-

plies. Consult local codes and regula-

tions to determine if the power supply/

strobe head combination complies.

NOTE

For maximum coverage and effectiveness, the 

light assembly should be mounted in a hori-

zontal orientation.

 

1.  Determine the desired mounting location for 

all the components. Before performing any installa-

tion, plan all wiring and wire routing.

NOTE

For maximum serviceability, position the 

flasher in a accessible location.

If shorted to vehicle frame, high cur-

rent conductors can cause hazardous 

sparks resulting in electrical fires or 

molten metal. Before proceeding, discon-

nect the positive (+) battery terminal 

connection(s).

 

2.  Install the light assemblies as described in 

the instructions packed with the units.
