Diode Dynamic SL1
I have had the SL1 in the car for a couple weeks now. They are not quite as bright as the HIDs they replaced, but dang close. These LEDs are white, without any tint of blue, and they are dramatically brighter than halogens .. I won't be going back to HIDs and all the issues associated with HIDs.
You want a bright, white LED that is reliable? The Diode Dynamic SL1!
