4.2 Wiring Instructions
The included wiring harness simplifies the electrical connection. Follow the instructions provided with the harness for specific wiring details. General steps include:
- Connect Lights: Attach the light connectors to the corresponding connectors on the wiring harness.
- Power Connection: Connect the positive (+) wire from the harness to the vehicle's battery positive terminal (or a fused accessory power source) and the negative (-) wire to a suitable ground point on the vehicle chassis.
- Switch Installation: Install the switch in a convenient location within the vehicle's cabin. Connect the switch wires to the harness as directed.
- Fuse Protection: Ensure the wiring harness includes an inline fuse for circuit protection. Verify the fuse rating matches the product specifications (1.63A draw per light, so total 3.26A for the pair, a 5A or 10A fuse is typically appropriate).

5. Operating Instructions
Once installed, operating your KC HiLiTES 643 Pro Sport LED lights is straightforward:
- Power On/Off: Use the installed switch to turn the lights on or off.
- Beam Patterns: The lights are available in spot (focused) or spread (wider) beam patterns. The chosen pattern will determine the light distribution.
- Aiming: For optimal performance, adjust the aim of the lights to suit your driving conditions. Typically, off-road lights are aimed to illuminate areas beyond the reach of standard headlights or to provide wider peripheral vision.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your LED lights.
- Cleaning: Clean the lenses regularly with a soft cloth and mild soap and water to remove dirt, mud, and debris. Avoid abrasive cleaners that could scratch the lens.
- Inspection: Periodically check all mounting hardware for tightness. Inspect wiring for any signs of wear, fraying, or corrosion. Ensure all connections remain secure.
- Housing: The Polymax housing is designed to be durable, but inspect it for any cracks or damage after off-road excursions.
7. Troubleshooting
If you encounter issues with your KC HiLiTES LED lights, refer to the following common troubleshooting steps:
- Lights Not Turning On:
- Check the fuse in the wiring harness. Replace if blown.
- Verify all electrical connections (power, ground, switch) are secure and free of corrosion.
- Ensure the vehicle's battery has sufficient charge.
- Test the switch for proper functionality.
- Dim or Flickering Lights:
- Check for loose or corroded wiring connections, especially ground connections.
- Ensure the vehicle's charging system is operating correctly.
- Moisture Inside Lens:
- Small amounts of condensation can occur due to temperature changes. If excessive, check for cracks in the housing or improper sealing. Contact support if the issue persists.
