Do you have a headlight bucket with no extra space behind the bucket? No problem, the back/connector side of our Native H4R2 is the same size as a halogen.

Back end physically fits where a standard H4 fits. Diameter of heat sink is slightly larger than Bosh Reflector Lamp opening. A Dremel with a sanding drum widened the opening by 1 millimeter and the lamp dropped in. (Or you could pay $10 extra for the reduced diameter version of this bulb)
Light is brighter and a higher color temp than standard tungsten lamp. There is a little dark wedge in the lower quadrant on high beam. But it is small and only shows up under very specific conditions.
Light is a good enough improvement that I'll probably add this bulb upgrade to my other two bikes. I'm interested to see just how long the tiny cooling fan built into the heat sink lasts.

Have had the H4R2 in my Honda CB1100 for a few weeks. Just bought a second one for my Bonneville, which is famous for having a very weak headlight. I had another LED in this bike, but the beam pattern was not excellent, and it only lit up the upper half of the headlight reflector. This bulb puts out a better beam, and gives a much brighter appearance to the front of the bike, which is good for visibility to other road users.

I was looking for an LED bulb that would fit in the tight headlight bucket on my Honda. Also, I was wary of a rear-mounted heat sink melting the wires that are tightly packed in my headlight housing. Also, I have an H4 LED bulb on my Bonneville, and the brightness of the headlight in daylight,and the beam pattern are so-so. This bulb fits in the same space as a halogen, doesn't direct any heat rear-ward, and the headlight is very bright in daylight, increasing visibility to cars, and casts a respectable beam on the ground at night. I've only had it for a few days, but I'm thinking of buying one for my Triumph.

Airheads are renowned for the poor stock lighting and low factory charging output. This led is a solution for both, works great and has restored my confidence in riding the ole BMW at night.

Easily fits in the small Xco headlight. Nice beam pattern and lots of light in the right places.

Simple install. Put outs a lot of light, very bright. Frees up some watts
