If you can find one of those 'button' type bulb flashers, they work great in edison base light fixtures....
Unscrew bulb, insert button in socket base, re-install bulb.
Use a 100 watt bulb, and amp clamp for a close to 1 amp pulse...that's the circuit.
Ringing out a new house, use a 'temp' socket at the lighting locations.
Dig around and find an old adaptor socket that plugs into a receptacle.....proceed as above.
Also, used the radio. In comm jobs, I had a 120 volt claxon horn! Not reccomended for an occupied resi job though.
