I got some h4 housings from bus depot a few years ago. I don't think they are
the same as any you mentioned. Mine have a flat face. They are great,
especially with relays driving them in my TR4A.
I have noticed recently a little foggyness on the inside of the lens. It will
likely be rather hard to clean off properly. Not sure why it happened.
I think that se of the newer H4 LED bulbs MIGHT have the emitters in a more
similar position to the filaments compared to the older LED designs. I not
sure how much of a difference it might make.
Ultimately, I think that there needs to bs a standardized LED emitter
location(s), so that reflectors can be made to match.
For now I will continue using real incandescent H4 bulbs and save a little
power elsewhere with LEDs
