Safety Messages
• DO NOT install equipment or route wiring (or the plug in cord) in the deployment
path of an airbag.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the
seat needs to be recalibrated for proper airbag deployment.
• Before mounting any components, check the manual to be sure that the
component you are installing is suitable for use in that area of the vehicle. Many
components are not suitable for use in the engine compartment or other extreme
environmental exposure areas.
• The service life of light bulbs and strobes tubes will be shortened if the
glass portion is touched during installation. Use gloves when handling these
components. If the glass portion has been touched, clean the glass carefully with
isopropyl alcohol.
• 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.
• Refer to the manual packed with the lighting system for proper electrical
connections, additional precautions, and information.
• 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 light bar mounting feet as close
to the outer edge of the roof as possible.
• Roof damage can occur if the hook adjustment bolts are over-tightened. On Arjent
and Vista light bars tighten the hook-adjustment bolts 10 ft-lb to 11 ft-lb. On all
other light bars tighten 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.
• To ensure proper operation, test all vehicle functions, including horn operation,
vehicle safety functions, and vehicle light systems. Ensure that the installation
has not affected the vehicle operation or changed any vehicle safety function or
circuit.
