H4...

[BenediktRochow at oaktech.com]

I had a brief look at the headlights of a new US-spec Mercedes G the other
day;
about 7" diameter, H4 bulb, and apart from the fluted or frosted top-3/4"
strip
and a bunch of writing at the bottom ("E12" in a circle, "DOT" - or "SAE",
memory
fails me - and lots of numbers), the lens was completely clear.

If this is legal, I wonder what else might be (I guess regular old H4
lights just lack
the DOT seal?) - and is it possible to buy generic-sized lights that work
this way?
Has anybody seen how these work?
Considering the "E12" mark, I'd guess these are used in Europe as well. Is
there
any word on how they compare to lights there?

thanks,
