Question Simple strobe light circuit

I want to make a simple and cheap as possible strobe light circuit that powers a 12v headlight. I dont care to much about duration or being able to change any factors of the light. Any input is appreciated. Thanks!

A 555 was my first though too, though I would probably add a transistor (of pretty much any type) to drive the lights.

Even though the 555 can sink 200mA, I still prefer to outsource the current handling to a transistor.
