Switch LEDs
I did a search for this but found nothing.
Anyone know part numbers (RadioShack, DigiKey, etc) for the amber and green LEDs inside the dash switches (fog lamps,. defroster)? I bought some from RadioShack, size matched and were the only ones, but the package doesn't indicate the voltage. Blew the LED as soon as I turned the switch on

Depending on the color, they only need between 2 and 3.5 volts.
Red, yellow, and amber only need 2.0-2.2 volts, while white and blue can handle upwards of 3.5.
You need to use a 680 to 1k-ohm resistor in line with either lead of the LED to drop the current/voltage down to a safe level.

Yeah I knew I'd probably have to do that, but hoping as a last resort. The switches have no resistors inline, just the LED in a little plastic holder that comes out.

kind of a pain, but its doable. the only other option would be to find a LED made for 12v. thoes usually have the resistor built in.

There is a lens, yes, but behind it is an LED. I'll take a photo next time I pull it apart (if possible). It looks just like the RadioShack piece I have too.
Hopefully I'll find the perfect match for those who need to replace the ones in their switches.
It is a relatively simple procedure - twist holder and remove bulb - and much better than spending $40+ for a new switch.
