Headlight failure again!

[Parky]

Hi,
I have put about 6000 miles on my r1100s and have got through 4 headlight dipped beam bulbs in that time.Can anyone tell me what I need to be looking at to cure this or is it just that boxer vibes that cause it to blow.It blew yesterday at the Mot station but was o.k. when I left the house.(new bulb wouldn't fit neither).
I tried a search but couldn't find anything.

Firstly I'd check the charging voltage across the battery (not overly easy on the S as it's under the tank) to make sure your reg/rec isn't going dicky. Sometimes the first symptoms of reg/rec failure is blowing bulbs...at least it is with a VFR.

Secondly, look to see if anything solid/vibe prone is touching the lamp housing as this might cause early bulb failure.

Mine popped again recently the same day it passed the MOT. Had 2 or 3 bulbs in 5 years...

Common fault for headlights going is a bad earth. So check the wiring and connectors and clean if necessary.

Thanks guys but where is the reg/rec?

Make sure your not touching the bulb glass with your fingers whilst fitting?

Thanks guys but where is the reg/rec?

It's mounted (car style) on the back of the alternator.

You're not putting in higher wattage bulbs are you to compensate for the shocking candlepower of the OE? I find those blow every 5 minutes on the S.

Standard bulbs my friend. I will take it to bits after the weekend as it is needed.
