Driver's side xenon - what to check?

[Darren S]

I park in an underground spot where the auto lights kick in on arrival.

On Friday night, I noticed it looked a bit dark from the drivers seat. I got out and saw that only the passenger side xenon headlight was on. I did the silly, obvious thing of tapping the headlight unit a bit, but the drivers side was definitely still off.

I switched off the car and when I came back to it yesterday - the lights both worked again? I don't think the drivers light going off the day before was a 'one off' - and I'm thinking something is on its way out.

Is there a process to check the components that go into a xenon headlight unit? Is there a part that normally fails more often than others?

Cheers.

French. :smiley:

Lol!

Tbf - its 11 years old and a daily. If this happened at 11 months, I'd be a bit pissed.

Well this is super creepy, I've just been out messing with my car and found the exact same issue, parked in an underground CP and the lights come on but the drivers side is much dimmer, wondering if it's a strange quirk of the Auto lights, maybe the car park is right on the edge of the Auto lights being on or off?
