I picked a harley one on ebay about a month ago for my 04 2 wheel dresser, from harley there about $550. paid $350. ITS the best money I have ever spent,This has two light bulbs in the single headlamp shell it came with a wiring harness & a ballast It was a good 3 hour job to put it in, when i got done the bike would not start so after about a hour of #@*#@! around I found out if you put the fuse in the in line fuse holder the bike will start right up It is like night and day difference over the stock light, I have bought all these other bulbs that claim they are so much better & brighter but really did crap?? I wish they made them for the ROAD GLIDE I would like to have one in my trike. The HD PART # IS 68094-06C
