Installed this bulb for my low beam in my GSX1300R after trying HIDS for more light. The bulb blew the doors off the HID. The motorcycle housing is not designed for HID so it just did not put out the light. This bulb is reasonably priced and WOW, it works!
I purchased both the H755-BP (55 watt) and the "brighter" H7100SW-BP (100 watt) bulbs. This review is for the H7100 bulb. I purchased both wattages in order to compare and hopefully benefit from slightly better illumination from the H7100. Bottom line is that both bulbs produce the same observed intensity. No perceived difference whatsoever. Both are definitely cheaper than the BMW OEM bulb system. But then I guess that would be expected anyway. Both fit perfectly fine in my F800GS.
