Would you be able to share the part numbers / sizes of the "new BMW head light bulbs"?
Sadly, my efforts mimicked those of others when it came time to adjust the Road Glide headlights. No matter what I did, I could never get the low beams to go out further. When I adjusted upward using the screws, it would come in contact with the clear lens in front. My solution was to order a pair of new BMW head light bulbs which throw out a much wider and higher low beam. Total cost about $25.00 delivered. Plug and play on my 2009 RG. No problems after 15 months or so in use. Made all the difference between night and day. Sorry for the pun, but it is true.
