What colour is the light? Could it feasibly be some other form of
discharge
lamp? Neons are commonly used in cheap automotive strobes. The good ones
have
the same as electronic camera flash heads...what's that, xenon?


The light for looking at the strobe lines on my DD75 is orange. Does it have
to be a special bulb? As long as you can see the lines clearly through the
little window does it matter?
