Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | Loose wiring connection, blown fuse, faulty switch, insufficient power. | Check all connections (positive, negative, switch). Inspect the in-line fuse and replace if blown. Test the switch for functionality. Ensure battery voltage is adequate. |
| Lights are dim or flickering. | Poor electrical connection, low voltage, damaged wiring. | Verify all connections are tight and free of corrosion. Check battery voltage. Inspect wiring for any cuts or damage. |
| Moisture inside the lens. | Compromised seal, extreme temperature changes. | Ensure all screws on the light housing are tightened. If moisture persists, contact support. Small amounts of condensation due to temperature changes may dissipate naturally. |
