I'm in my dash for other work and thinking about changing my dash lamping over to LEDs. The clock face on the glove box door is hard to read at night due to bulb placement behind clock face. Knowing that LEDs are not very sensitive to voltage change, output wise, once they turn on, how do you guys get them to change in light intensity. My current thinking is I will have to build a circuit that controls a bank of leds that light as I turn up the voltage at the dash rheostat. Anyone got a schmatic for this sort of thing. Thanks
