I have seen ideas from a couple of coilers about using LEDs and neon lamps as 
well as Terry's modified strobe light for checking and aligning sync rotary 
gaps.  Has anyone thought about modifying one of the hand held laser pointers 
to do this?  They have plenty of intensity (for a sort of dark room) and are 
only about $8.00.  Not sure what would be involved in the modifications to 
get it to fire on the 60 hz line frequency.  These are LED devices are they 
not?  Typically using three batteries for a 4.5 volt power supply.
