Lights On Signal - How?

So Im a dummy an constantly leave my fog lights and corner lights on when I get some place. This morning at school I left them on because it was still dawn-ish. The thing is I have no warning signal in the car to let my dumbass know I left my lights on. How do I get one? The fuses are fine, checked 'em. Im not sure I have a signal for the lights though..can I splice it into the keys in ignition signal, if so, how?
ideas?

Get one of these

woorrd!

yeah, that's a ripoff, they charge you $7 shipping when the parts only cost like $2 from radio shack. All it is is a mini buzzer that you connect to your fuse box. 2 wires, it couldn't be simpler.
