LED headlights have been my latest obsession. It started with trying to find more info on the Carmagic headlights. I've had no luck finding any useful info on the Carmagic lamps but at the price they are charging, I suspect they may be Chinese knockoffs. I did find a whole bunch of useful info on the
Youtube channel by 'Headlight Revolution' No surprise, there is a lot of BS out there and not all LED lamps or bulbs are created equal. Take home message is that when retrofitting LED bulbs in housings, it is important that the LED diodes are precisely placed to match the location of the original incandescent bulb or the beam pattern gets screwed up. A lot of bulbs fail that requirement.
After WAY too much time watching and reading reviews and test results, I've decided to buy a pair of
Hella Vision Plus H4 housings (DOT certified) and install
GTR CSP Mini H4 LED bulbs in them. Those are about 2.5x brighter than halogen while maintaining the correct beam pattern and consuming only 16w so don't use a cooling fan. The complete package will also be about 2/3 the price of the mystery Carmagic lights. If I wanted the brightest bulb, I'd get
GTR Ultra 2 bulbs, but they are 41.5w, and I don't want to have to run more wire for a relay.
Obviously, I don't have any actual experience with these, it's just what I've settled on after a lot of research.
