Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light bar does not turn on. | No power, loose connection, faulty fuse in cigarette adapter. | Check if the cigarette adapter is fully inserted. Verify vehicle's power outlet is functional. Inspect the power cable for damage. Check and replace the fuse in the cigarette adapter if blown. |
| Some LEDs are not flashing or are dim. | Damaged LED chip, internal wiring issue. | Contact customer support for assistance. Do not attempt to repair internal components yourself. |
| Light bar is not securely attached to the roof. | Dirty mounting surface, weak magnetic adhesion, damaged suction cups. | Clean the vehicle's roof and the magnetic bases thoroughly. Ensure suction cups are intact and properly seated. For high-speed applications, consider fixed mounting options if available. |
