If you are in a car, traveling at the speed of light, what happens when you turn on the headlights?

Update: Creed, yes I could, and yes they would. I'm inventing a car that travels at the speed of light, I was simply wondering what I could expect when I turn on the headlights.
Update 2: Uhm. I going to invent a car that goes faster than the speed of light. So forget that theory of relatively stuff. I'm going to prove it wrong. Just watch. Oh wait...you can't, I'll be moving too fast. Bahahahaha
