Try these addresses http://www.spectrumled.com/ and
http://www.superbrightleds.com/ I have dealt with both these companies
and can recommend each. Especially interesting is the 12VDC 1156/T10
PCB LED Lamp offered by Superbright. You can remove the bayonet base
from this lamp and wire it direct (observing polarity).


I looked at that light, I was a tad disappointed that the array simply
used a bunch of dropping resistors, to current limit the LEDs rather
than a PWM controller or constant current supply.

I am in the process of "rolling my own" array with some 5000mcd
superbright whites, and a pic based PWM controller, which, theoretically
at least, will give a nice smooth brightness control from 0-100% on,
without wasting power and heat on dropping resistors.
