[Yaesu] FRG-7

Mark,
  You can get the schematics at:
http://www.crocuta.com/FRG7/index.html

I believe that you can use any sort of 12V grain of wheat bulbs =
available at Radio Shack or your local electronics store.  You can do  a =
quick check by looking at the voltage across S6 which is the light =
switch.

2 hints:
1. Put a dropping resistor after S6 to lower the voltage to the light =
bulbs, then they will last much longer.
2. Use white LED's in series with an appropriate resistor.  They cost =
several dollars each, but you will never have to replace them again.
