This is a simple 555 circuit. Might also work with light bulbs. See the PDF schematic on the site. Power it with a 7812 regulator circuit for bulbs or a 7809 etc. for LEDs.

 

I have a circuit in my note book which is a little bit different,does the same thing. An alternative is to use a single flasher and power a relay coil instead,then power the bulbs with capacitor discharge with the contacts. Gives a cool flashing effect for light bulbs.
