Integrity Lightbar

•   When drilling into a vehicle structure, be sure that both sides of the surface are clear of anything 

that could be damaged. Remove all burrs from drilled holes. To prevent electrical shorts, grommet 

all drilled holes through which wiring passes. Also, ensure that the mounting screws do not cause 

electrical or mechanical damage to the vehicle.

•   Because vehicle roof construction and driving conditions vary, do not drive a vehicle with a 

magnetically mounted warning light installed. The light could fly off the vehicle causing injury or 

damage. Repair of damage incurred because of ignoring this warning shall be the sole responsibility 

of the user.

•   To avoid denting the roof of the vehicle, place the lightbar mounting feet as close to outer edge of the 

roof as possible.

•   Roof damage can occur if the hook adjustment bolts are over-tightened. On Arjent® lightbars tighten 

the adjustment bolts 10 ft-lb to 11 ft-lb. On all other lightbar models torque the adjustment bolts  

6 ft-lb to 7 ft-lb. Install keeper plates.

•   Locate the light system controls so the VEHICLE and CONTROLS can be operated safely under all 

driving conditions. 

After Installation or Service

•   After installation, test the light system to ensure that it is operating properly.

•   If a seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to be 

recalibrated for proper airbag deployment.

•   Test all vehicle functions, including horn operation, vehicle safety functions and vehicle light 

systems, to ensure proper operation. Ensure that the installation has not affected the vehicle operation 

or changed any vehicle safety function or circuit.

•   Scratched or dull reflectors, mirrors or lenses will reduce the effectiveness of the lighting system. 

Avoid heavy pressure and use of caustic or petroleum based products when cleaning the lighting 

system. Replace any optical components that may have been scratched or crazed during system 

installation.

•   Do not attempt to activate or de-activate the light system control while driving in a hazardous 

situation.

•   You should frequently inspect the light system to ensure that it is operating properly and that it is 

securely attached to the vehicle.

•   After installation and testing are complete, provide a copy of these instructions to instructional staff 

and all operating personnel.

•   Do not use a pressure washer to clean the lightbar. Failure to heed this notice will damage the lightbar.
•   File these instructions in a safe place and refer to them when maintaining and/or re-installing the 

product.

Failure to follow all safety precautions and instructions may result in property damage, serious injury,  

or death.
