A friend who was into hot rods mentioned that you can buy spark plug caps that flash whenever there is a spark and that they work by having a neon bulb mounted close to but not touching the high tension wire.octane wrote: How on earth did you come up with that!
I put 2 & 2 together & stuck a neon bulb in the end of a piece of tubing.
No, halogen lights (more properly called tungsten-halogen or quartz-halogen) are simply more refined incandescent bulbs. They have a tungsten filament in a quartz glass envelope filled with halogen gas.BTW I guess it's what we over here call a halogen bulb????

Neon lights are the types that you often see signs made of - the ones with a clear tube that glows reddish orange when turned on and can be bent into shapes & letters. They work by exciting neon gas between 2 electrodes mounted inside the glass envelope. The envelope can be several feet long or the size of a flashlight bulb, as long as the appropriate voltage for the distance between the electrodes is applied.
