IF you wish to flash it very quickly, you will not be able to TELL that it is flashing. It takes a second or two for the filament to cool down and stop emitting light. If you wish to flash it once a second or slower, then Skinnerz suggestion is good. IF one is using a neon bulb, a large resistor and a capacitor can be used to make the circuit flash.

The best solution is to find a 555 timer circuit (there are hundreds of examples), and use it to switch a suitable relay.
