MOT is the UK anual inspection for roadworthyness. That includes a check of operation of lights.
The rhs looks a bit tighter for space than the lhs (from the cabin) because of the aircon compressor and the hoses. I "fixed" the problem anyway. I removed and reseated the red and orange relays (headlight and monitoring) and checked the bulbs in the left hand side.
The headlight bulb was a little slack and the clip wasn't pressing it into place too well. A little wiggle and all good again.
I think it was just the relay contacts corroded a little, removed and refitted the red and orange relays and all good, headlight pictograms off and with a wiggle of the bulb both lights working. Took it for a drive down a nice bumpy road that is typical of the potholed uk tarmac and it is still fine.
