Has anyone converted their instrument panel illumination lights to LEDs yet? They are being sold as upgrades and are supposed to make the instruments brighter (good for these older eyes). I know the 2 watt bulbs can be replaced with 4 watt bulbs, but I was warned by North Hollywood Speedometer not to do it as the extra heat generated will eventually fry the innards of your instrument. I like the idea of brighter instruments however.

If I were doing this I would dim them with PWM in response to the voltage change across a voltage divider formed by the dimmer knob and a dropping resistor. The downside is you would need a custom circuit to connect all the LEDs to and you wouldn't be able to use them as a drop in for regular light bulbs. (Unless you included a tiny dc-dc converter and the pwm circuit inside the base of each bulb.)
