I was thinking that it would be really cool if I could push a button inside the car to make one headlight, with the lights on, close and open like a wink. How would I be able to do this? I'm thinking that it should be as easy as having a normally-on button on a +12v lead, but I might be wrong. What should I do? It's a 1988 Prelude 2.0Si 4WS.

Thanks everyone!
