If the idea is to mimic a motor vehicle or to make people think you operating a motorcycle or automobile then you are likely going to be on your own in terms of products, mounting and wiring. I don't think it practical to have a five or six inch glass bulb on a bicycle. Maybe Nightsun or some other manufacturer makes something - I really don't know and could very well be wrong.
Modern LED lighting won't mimic a motor vehicle but they are really bright, as bright or brighter than a car. A motorist would have to be dead to not see you. I recommend looking at the Light & Motion Urban series. Others have favorites and the guys in the electronics forum will not be shy about telling you about their lights.
