LED Light Flickering
The two big issues that we encounter are a lost connection or headlights that are not driving much power. Therefore what you need to do is:
- Check all of the connections properly.
- Install the anti-flicker harness.
- Due to the tight attachment, it is necessary to switch the faulty headlight to the other side while leaving the connector on the main side.
- But, finding that the headlight no longer flickers indicates a faulty connector or a loose connection.
- Additionally, you may need to uninstall the anti-flicker program to see whether the lights work without it.
Single Light Working
A faulty connector or a loose connection is also to blame for turning off one light but not the other. Resolve by following the given steps:
- Only switch the headlight to the opposite side and check the connector and anti-flicker on the main side.
- Checking the lights on the opposite side indicates a faulty part or a loose contact.
- As a result, you must change the connector to the functioning side. If you are unable to fix the problem, the problem is a faulty connector. Install anti-flicker software to solve the problem.
- Remember, when the metal tabs are bent, it indicates a faulty connection.
- Verify the plastic harnesses that the connector and the anti-flicker have to ensure that the metal part has a direct correlation between the factor harness and the aftermarket component.
- Alternatively, the one light bulb fuse will necessitate the replacement of a new bulb.
