Setup and Installation
1. Mounting the Light Bar
The Pro6 Gravity 4 LED Light Bar features a patented Infinity Ring system, allowing for configurable and modular mounting. Choose a secure location on your vehicle, such as a roof rack or bumper, that provides optimal light projection and does not obstruct the driver's view.
- Assemble the mounting brackets to the light bar using the provided hardware. Ensure all bolts are tightened securely.
- Position the light bar on the desired mounting surface. Mark the drilling locations for the mounting brackets.
- Drill pilot holes as necessary and attach the light bar to the vehicle using the appropriate hardware. Use washers and lock nuts to ensure a firm attachment.
- Adjust the angle of the light bar to achieve the desired beam direction. Tighten all pivot bolts once the angle is set.

2. Wiring Instructions
The light bar comes with a pre-assembled wiring harness for simplified installation. Ensure the vehicle's battery is disconnected before proceeding.
- Connect the positive (+) wire from the light bar harness to the positive terminal of the vehicle's battery.
- Connect the negative (-) wire from the light bar harness to a suitable ground point on the vehicle chassis or the negative terminal of the battery.
- Route the wiring harness through the vehicle's engine bay and into the cabin, ensuring it is protected from heat, sharp edges, and moving parts. Use zip ties to secure the wiring.
- Mount the included switch in a convenient location within the vehicle's cabin. Connect the switch wires according to the harness instructions.
- Reconnect the vehicle's battery. Test the light bar to ensure it functions correctly.

Maintenance
Regular maintenance will ensure the longevity and optimal performance of your LED light bar.
- Cleaning: Clean the lens and housing regularly with a mild soap and water solution and a soft cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish or lens.
- Inspection: Periodically check all mounting hardware for tightness. Inspect wiring for any signs of wear, fraying, or corrosion. Ensure all connections remain secure.
- Water Resistance: The light bar is water-resistant. However, avoid directing high-pressure water sprays directly at the seals for extended periods.
Troubleshooting
If you encounter issues with your KC HiLiTES Pro6 Gravity 4 LED Light Bar, refer to the following common troubleshooting steps:
- Light Bar Does Not Turn On:
- Check all wiring connections for looseness or corrosion.
- Verify that the vehicle's battery has sufficient charge.
- Inspect the fuse in the wiring harness (if applicable) and replace if blown.
- Ensure the switch is functioning correctly.
- Dim or Flickering Light:
- Check for poor ground connections.
- Inspect wiring for any damage or partial breaks.
- Ensure the vehicle's charging system is operating correctly.
- Moisture Inside Lens:
- While the light bar is water-resistant, extreme temperature changes can sometimes cause condensation. This usually dissipates with use. If persistent, inspect seals for damage.
If these steps do not resolve the issue, contact KC HiLiTES customer support for further assistance.
