Sorry to inform you but to my knowledge there is no way to turn off the headlights without turning off the ignition. This is an issue only on the 99's because evidently after that GM realized people wanted to turn them off. I have a 99 and an 02 and the 02 is the only one of mine the lights can be turned off on.
