I did the modification this weekend. I followed the example of this link. http://www.burgman400.it/forum/viewtopic.php?t=7355&start=0
I then used a plug and go H4 headlight modulator from Comagination on the left side with an H7 Silverstar Ultra bulb, and a Velocity V-HID 5000K kit on the right side. I wanted to have the modulator, as I do a lot of urban commuting, but I did want brighter lighting to see the Michigan deer at night. Were #2 in the country for deer accidents; here is the top ten. http://money.cnn.com/2005/11/04/news/newsmakers/deer/
So I went with an HID to complete this two side combo. Both kits were very easy to do, The hardest part of the job was the tupperware.
