Mr Christmas light set

A set that has been largely disused, I never remembered it ever being in use. One of the days i was rummaging through all the sets in the loft and came across it. I dragged it down and plugged it in, only the blue line worked, which made me suspect they were flash lamp controlled. Replacing the flash lamps got the whole set working, with the odd one or two here and there out. replacing those as well, they now take place in the front bedroom window. Naturally I coloured the flash lamps in with permanent marker, the lamp colour they control.
