Highlander Extreme Edition Upgrade Tiger Navigation Atmosphere Lights Out

The reasons why the car ambient light does not light up are as follows:

1. The ambient light switch is not turned on: check whether the ambient light switch is turned on to ensure the connection is safe and stable.

2. Circuit failure: If the switch is normal but the light is still off, it may be a circuit failure or poor line contact. You can check whether the power supply, signal and ground wire of the navigation system are firmly connected.

3. Bulb failure: If the navigation system circuit is normal, it may be caused by the failure of the bulb itself.
