You can get 'em as bulb sets from PIAA. They are bright, they are
efficient and the light (as seen from driver's perspective) is
quite YELLOW!!! This may (or may not) make a difference.
I was going to put one in my K100RS. The PIAA guy at the auto show
warned me about the color. I bought a 100/135 W H4 bulb instead...
