Excuse my ignorance here but rather than try adjusting the light intensity of an LED (which is something it is not designed to do), why not just double the number of LEDs in a cluster and use half for tail lights and then all for brake lights. It would be simpler and safer than driving with LEDs at low brightness. Hey! I'll patent the idea! Oh damn! I've let everybody in on the secret now.... oh well, there goes my money making plan.....
