I think they are making them in H4 size now.

it uses a 9003 lamp. not sure if that crosses to an H4 or not. i have been running the regular silverstars for a while. the ultra was not available when i bought the silverstars.

I would hope the "Ultra's" last longer than the regular Silverstars.

H4: European / Japanese spec
9003: US spec
They're basically interchangeable, the main difference is in the lamp reflector that they go into: Europe: asymmetric light that illuminates road edges without blinding oncoming vehicles, US: symmetric light that blinds oncoming drivers without illuminating the edges.
