BTW, no LED headlight replacement bulb is DOT approved for highway use. None. Nada. Zilch. LEDs can't place the light in the exact same registration as a halogen filament, meaning lamp assemblies designed for halogens will project a different pattern with LEDs - usually with significantly more glare to oncoming traffic. The same applies to retro-fitting HID bulbs to lamps designed for halogens.

The only legal, DOT-approved, approach is to replace the entire headlight assembly (lens, reflector, LED light source) that's designed around the LED.
