I recently installed two of these LED bulbs in my Vision headlight and I must stay they are fantastic! you have lots of room to manuver the fins and they fit with ease.
I also installed one of these in my HID location and it also fits really nice and its bright
The above LED also comes with color jells to give you the option to change the color of the light. I went with yellow as it sets the front of the bike out from everything else.
Took me less than 30 min to change out all three (just removed the air filter and had no issues)
