- LED Functionality: Regularly test the running light, brake light, and turn signals to confirm they are all working correctly.
Troubleshooting
If you encounter issues with your KEMIMOTO License Plate Bracket, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| LED lights not illuminating. | Loose or incorrect wiring connection; Blown fuse; Faulty LED unit. | Check all wiring connections for proper contact and polarity. Inspect the motorcycle's fuse box for a blown fuse and replace if necessary. If wiring and fuse are good, the LED unit may be faulty and require replacement. |
| Lights are dim or flickering. | Poor electrical ground; Loose connection; Low voltage. | Ensure the ground wire is securely connected to a clean, unpainted metal surface on the motorcycle frame. Check all connections for tightness. Verify the motorcycle's battery voltage is adequate. |
| Bracket feels loose after installation. | Mounting bolts not tightened sufficiently. | Re-tighten all mounting bolts to the recommended torque specifications. Apply thread-locking compound if desired for added security. |
| Turn signals flash too fast or too slow. | Incorrect load resistance for LED signals (hyper-flashing); Relay issue. | This kit is designed not to require a load equalizer. If hyper-flashing occurs, consult a motorcycle electrician to check the flasher relay or add appropriate load resistors. |
