Setup and Installation
This light bar system is designed for a vehicle-specific fit, particularly for Ford F-150 models from 2015-2020. Professional installation is recommended.
- Preparation: Park the vehicle on a level surface and engage the parking brake. Disconnect the negative terminal of the vehicle's battery.
- Mounting Bracket Installation: Identify the correct mounting points on your vehicle's bumper or grille area as per the vehicle-specific instructions (not included in this general manual). Securely attach the provided mounting brackets using the supplied hardware. Ensure brackets are aligned and tightened to vehicle manufacturer specifications.
- Light Bar Assembly: Assemble the individual Gravity LED Pro6 light modules onto the main light bar frame, ensuring all connections are secure. Attach the assembled light bar to the installed mounting brackets. Adjust the angle of the light bar as desired for optimal light spread, then tighten all mounting bolts.
- Wiring Harness Connection: Route the wiring harness from the light bar to the vehicle's battery and interior switch location. Connect the light bar's power input to the harness. Connect the positive lead of the harness to the positive terminal of the battery (via an inline fuse, if not pre-installed) and the negative lead to a suitable ground point on the vehicle chassis.
- Switch Installation: Install the included switch in a convenient location within the vehicle's cabin. Connect the switch wires to the wiring harness as per the harness's color-coded instructions.
- Final Checks: Reconnect the vehicle's battery. Test the light bar's functionality. Ensure all connections are secure and no wires are pinched or exposed to moving parts or excessive heat.
Operating Instructions
To operate your KC Hilites Gravity LED Pro6 Light Bar:
- Ensure the vehicle's ignition is in the "ON" or "ACC" position, or the engine is running, depending on how the light bar was wired.
- Locate the installed switch inside your vehicle.
- Flip the switch to the "ON" position to illuminate the light bar.
- Flip the switch to the "OFF" position to turn off the light bar.
Note: Always be mindful of local laws and regulations regarding the use of auxiliary lighting on public roads.
Maintenance
Regular maintenance will ensure the longevity and optimal performance of your light bar:
- Cleaning: Clean the lenses and housing regularly with a soft cloth and mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the finish or lens.
