7. Troubleshooting

7.1. Common Issues

  • Lights not functioning or partially lit:
    • Check all wiring connections, especially the 4-pin connector and the reverse light wire, to ensure they are secure and properly seated.
    • Verify that your vehicle's 12V DC power supply is active.
    • Inspect the light bar for any visible damage or cuts in the silicone housing.
  • Incorrect signal behavior (e.g., turn signals not sequential, random flashing):
    • Ensure the light bar is connected to the correct vehicle wires for each function (running, brake, turn, reverse).
    • Some vehicles may require an LED-compatible flasher relay to prevent hyper-flashing or incorrect sequential behavior. Consult a professional if issues persist.
  • Brake light delay:
    • This can sometimes occur due to vehicle-specific wiring or relays. If the delay is significant and affects safety, consult a qualified automotive electrician.
  • Light bar falling off:
    • Ensure the mounting surface was thoroughly cleaned and dry before installation.
    • Re-apply pressure to the adhesive strip.
    • Utilize the included mounting clips and screws for a more secure attachment.
