Anyone ever have a light go out? How do you determine if it is the bulb or something else? Where is a good source for parts?

 

you could swap right and left to check. If you want to buy an aftermkt bulb there are hundreds of lighting dealers. Just put in a search for hid or xenon bulb and youll get endless stores. or do it on ebay. A factory bulb may cost $ 100 + ea. and a after would be $30 + a pair. Ive used several and same quality so far.

 

usually its the switch.

 

It was a fuse.

There's an old saying; when you hear the sound of thundering hooves, don't assume it's zebras.
