The idea behind the project was the dilemma one would face of what to do with a blown light globe. I did some searching and found on The Lighting Outlet website some incandescent light globes (with a fillament) I ordered two and I thank you for the extra three globes which you gave me free of charge. I tapped one of the globes on a table to dislodge the filament . I sourced a lamp holder for the globe, an auto ignition coil and a horn relay as a vibrator all mounted on a small bread board. The car coil and relay work to generate a high voltage to connect to the globe which now has a spark gap. The high voltage generates an orange spark in the globe. Cheers David Law 0481 098 785.
