Just replaced both xenon bulbs about 6 months ago. Came out this morning to my right headlight not working. Went to change bulb and noticed that the round protector cap that covers the bulb enclosure had fallen off. Replaced bulb, still no joy. Now, we have had a lot of rain over the last few weeks so I think the enclosure may have been exposed, so don't know what to do now. I checked all fuses they seem OK. Any one experience anything like this before?
Hopefully it'll dry out.. Fingers crossed
