I just PM's one of the poster's thread who gave a very detailed version of how to change the low beam Xenon bulb.
I asked him WHY does the entire headlight have to be removed?
Seems like removing the rear dustcover would give you access to the Xenon bulb to change it.
Any thoughts? I am waiting on the the thread poster to get back to me on this one b/c I need/want to change out both mine for a bit brighter ones due to my very poor night vision.
