That's a problem when your light source doesn't geometrically match the reflector design specs. If the lamp was designed to have all the light coming from one small hot wire filament, ditching that and replacing it with 30 LEDs positioned all over is going to ruin the focus. It's a problem with HID conversion bulbs, and I've got to assume it's a much bigger problem with an LED array that looks like I stuck emitters all over my thumb.EldRitch wrote: I'm still up in the air on the LED headlights. Those that I installed seem to waste a lot of light on the right side off the road, and this makes the eye see more light, so your pupil contracts, and you don't see as much on the road. I may go back to the brighter Philips incandescents.
Here's an article Daniel Stern wrote about the subject many years ago:
