a 12v to 16vdc lamp works ( LED might work but really is too sensitive)
20MA is best not 1 amp,but way less.
is best, that way leaking transistors can be seen to fail.

one good lamp is cluster idiot lamp or back ground lamp using in the speed cluster wired up as noid lamp with 2 clips .
a ge194 lamp seen in walmart may work good. 0.25amps 3watt , lower watts is best for testing but no too low as LED are.
transistor can be good or bad and bad 3 ways shorted , open or leaking. (I always not to find all 3 including leaking) glows dim and wrongly that.
