I popped in some 7th Gen Sirius LED's in my '75 Beast. Love the light, they are in Euro H4 housings. Amazingly bright...I have the same wonderful results as above....just remember the quote above is a must. I had read this thread (which is why I bought them) and missed this key piece of info. So I initially installed them without a heat sink....and tested them for a few minutes. I then re-read this thread and re-discovered this gem on info.....which then had me pulling and re-doing the lights.
I am not sure running without the heat sink for a single evening test drive would have hurt them.....but REMEMBER THE ADVICE ABOVE and all will be well in your LED Headlight world.
