Graphic display shows occasional o/s rear or brake bulb failures.
Warning could come on, then a mile down the road go off again. A few minutes
later it might come back on.
Only just started BTW. For the last year it's been fine with the same bulbs.
All rear bulbs have been checked when warning was showing, and all are
working. Have removed and refitted bulbs, and tried swapping similar bulbs.
Nothing seems to make any difference.
I'm now thinking sensor module, relay, whatever.
I'm probably misnaming it or something, but googling doesn't come up with
any info that might solve the problem.
Any suggestions welcome.
