Peugeot 207 Erratic Lighting Fault

Hey, I also have a 207, and it sounds similar to what I went through. The headlight switch was acting up. Did you check the dimmer switch too? That's a common culprit. Does it happen all the time or only sometimes?

Thanks! The dimmer switch seems ok visually. I've not been able to reproduce the issue consistently - it seems rather random. Is that the same behaviour you saw or did it degrade from intermittent to permanent?

Yeah, mine was intermittent at first too, then it got worse over a couple weeks. Honestly, messing with the electrics is a pain. I ended up taking it to a workshop; they said it was the switch and some dodgy wiring. Saved myself a headache.

Appreciate the confirmation. Sounds like it's best left to a professional then. I've booked it in for next week; they are quoting 95€ to replace the switch and fix the wiring. Thanks again!
