6. Fejlfinding
If you encounter any issues with your LASFIT LED bulbs, please refer to the following common solutions:
- Pæren lyser ikke:
- Sørg for, at pæren sidder helt i fatningen.
- Due to polarity sensitivity, if the LED does not light up, remove it, rotate it 180 degrees, and reinsert.
- Check the vehicle's fuse box for any blown fuses related to the lighting circuit.
- Hyper Flash or Error Warning on Dashboard:
- While LASFIT bulbs are designed to be CANBUS error-free, some highly sensitive vehicle systems may still trigger a warning. Ensure the bulb is correctly installed.
- If hyper flash persists, verify that the bulb type is correct for your vehicle's specific application (e.g., 7443 for brake/tail, not 7440 for turn signal if it requires a different resistance).
- Dæmpet eller ujævn lysudbytte:
- Ensure the bulb is clean and free from debris.
- Verify the bulb is fully seated and making proper electrical contact.
If these steps do not resolve the issue, please contact LASFIT Customer Support.
