Lexus LX Lights Switch On By Themselves

Hi, I have a 2010 Lexus LX with a gasoline engine. I'm having an electrical problem with the lights. The lights sometimes switch on by themselves, and I got an error code stored. Could a defective cable or plug connection cause this?

It's possible. Faulty headlight switch operation and stored error codes suggest an electrical issue. Have you checked the fuse box for any blown fuses related to the tail lights or headlight switch? That would be a first step.

Thanks for the tip. I will check it. If the fuses are alright, could the headlight switch itself be the problem?

If the fuses are fine, then yes, the switch itself could very well be the culprit, or perhaps a short circuit. Given the stored error code, it's probably best to get it checked by a qualified workshop.

Thanks for the advice! I took it to a workshop and you were right. It was indeed a defective connector. They replaced the connector and the light switch works fine now. The repair cost was 95€.
