Newer Judges do in fact use LEDs and therefore if a light isn't
working it's a wiring problem, most likely...the Classic Judge uses
a a 2-watt bayonet-connection bulb available at most Radio Shacks.
Oh, and all Judges use transistors, but the Classic Judge uses a
slightly weird fast-switching transistor...I found this out the hard
way when I tried to fix ours.
