Too bad I recently finished installing relays to get my incandescent bulb voltage up. Wasted effort if I want to go with these LEDs.
One way to extend the longevity would be to switch in a resistor during the day when the ambient temp is high, thus limiting current when you don't really need to illuminate the road. Switch it out at night time when temps are cooler.
I hate blue headlights with a passion. I spent some time in France where all car headlights are yellow. That is much better for cutting through fog, yet it is easier on the eyes of oncoming drivers. I bought some yellow bulbs for my car here in Oregon and got pulled over by a cop for having non-standard bulb colors. Oh well, I guess my consideration for my fellow drivers was not wanted!
