I also have a 1999 Chevy, heres the trick on your lights, shut the motor off, press the emergency brake pedal down just a little, an inch or so, restart the truck and your lights will stay off, you can turn on the parking lights with the switch, once you pull off the ramp, just release your emergency brake and you lights will be on. This will not do any damage to your truck or brakes because you have not fully set the brakes. I have been doing this sense my truck was new in 1999, I just put the fisrt set of brakes on my truck and it had 75,000 miles on it.
PS if your light still come on when you start the truck, just repeat the step and push the emergency brake down a little more.

Good luck and good fishing
