I didn’t know that EL LED wire was high voltage.
I was looking at those mains voltage doubler TLs, but it just seams too dangerous and not portable.
Things are getting dangerous now because my 400V PS arrived. 
My cheap 9 LED torch with a direction reflector also got here, so just waiting for the COB before I test Peter’s LED TL. I’m interested if the 555 adds lag to the trigger, and I need a lot of light to direct it at the engines accurate timing marks because you can’t get close enough for a weak light.
I remember reading a timing light test in a car mag years ago - maybe a decade - and pretty much all had lag. From memory the cheaper the more lag, but even the expensive SnapOn had 1º lag.
EDIT - Holly carp, 10V in 655V out!.
