Lightening 12V Car Headlight Bulb?

Is there anyway of lightening the 12V bulb inside the car Headlight? Anybody done such a project?

i should have used lightening up. Well i actually meant to power up the 12v headlight bulb. How to connect that to Arduino and then power it up?

You would need a relay or a transistor that can handle the current drawn by the 12 lamp, and an external powersupply.
