I had a bulb failure a few months back - drove me crazy because for the life of me I couldn't find see which one it was.

Turned out I wasn't going crazy and I didn't have any defective bulbs - the bulb carrier to the rear light cluster was faulty and was giving an untrue reading.

If you can't see a blown bulb my money is on the bulb carrier being deffective. When I raised this point back in Feb when it happened there were a few other members who had reported the same, so it seems to be a common(ish) fault on e92'S.
