Guest Posted November 12, 2013 Share Posted November 12, 2013 The bulb in my XVS1100 blew the other week. I picked up a cheapy replacement and it blew almost straight away. It was only £1.99 from The Range, so I put it down to being a cheap and nasty bulb, and the bike being a thumper, the vibrations. Bought a decent one (OSRAM Night Racer Plus H4). This lasted a day before breaking (both main and dipped). I have of course been ultra careful when fitting them to not touch the glass etc. Fitted a 3rd bulb and will see what happens, Is there something else I should be looking at? Thanks.

Moderator Airhead Posted November 12, 2013 Moderator Share Posted November 12, 2013 Perhaps your regulator isnt working properly, It wont do the battery any good if it isnt Link to comment Share on other sites More sharing options...
Moderator DirtyDT Posted November 12, 2013 Moderator Share Posted November 12, 2013 As above or a short in the wiring somewhere. You need to check the volts going to the bulb at various revs and when switching from low to high beam. Link to comment Share on other sites More sharing options...
Guest Posted November 13, 2013 Share Posted November 13, 2013 So can I should unplug the headlight stick a DVM on the plug measure with engine off and revving see what the difference is?Sent from my Nexus 7 using Tapatalk 4 Link to comment Share on other sites More sharing options...
slice Posted November 13, 2013 Share Posted November 13, 2013 Just use the usual multimeter and test to see what the output is at the plug, low and high revs, if it's over the proscribed limit it's the regulator most probably.
