A battery in series with a (LED + Resistor / light bulb) and an on-off button. Arbitrary frequency and duty cycle. As long as your finger lasts, I guess (though it is the simplest!)

...Okay, so the next step up would maybe be a 555 timer in astable oscillator mode (Google for 555 timer, or 555 square wave).

And PLEASE refrain from applying text effects to your entire post. Especially if it's just to make all the text really big.

EDIT: Just a friendly notice to allow people to actually read your posts.

Just goole with "blinker", "Astable Flip-Flop". Does this one suit you?

Though it uses LED, but you could use a low current light bulb as well in the place.

diiode?? What is it? Do you want to say LED (Light Emitting Diode)?
