Jim,

From info I have located on the internet, I have cobbled together a
circuit diagram for illuminating my instrument panel using LED's. I was
wondering if I emailed you a copy, would you would be kind enough to
take a peek at the circuit and see if I missed anything? Electronics
isn't my expertise but I enjoy it all the same.

Thanks in advance,
Charlie Smith


charlie, assuming that you are using a 12 volt bus, all you need to do
to use an LED is put a 680ohm resistor in series with it.
so if you had an instrument that was lit by a small tungsten globe, in
theory, all you need to do is take out the lamp holder and wire in the
led and the resistor in its place. the led should then work with the
original switching.
you need to have a resistor in series with each LED. so if you use a
number of LED's in the panel each must have a resistor in series with
it.
simple enough isnt it.
