It is possible to have LED lights designed and built to specification but I now think it will not be necessary. I have already found CREE MT-G2 LED Angel Eyes which would probably be my first choice for brightness. CREE XM-L2 is another good option but is a smaller LED so may not be as bright unless there are 4 x XM-L2s vs 2 x MT-G2s, I will check and compare. The other issue is we will need to make sure they run cool enough as brighter Angel Eyes means running the LEDs at higher power which means more heat so cooling will be crucial otherwise the LEDs will not last long. This means using larger passive cooling finned heatsinks or active cooling devices like the fan on your CPU. Anyway, I can check all of this for us and make sure the LEDs are running within manufacture specified operating temps. If so, they should be able to last longer than the car and you will never have to replace a light bulb again.
