When my headlights are off my taillights work fine. Once I turn my headlights on my left rear brakelight stops working and when I use my turnsignals they work but my backup lights flash opposite the signal flash. The alternate signal and backup light flashing also happens when I use my hazard flashers. But, when I turn my headlights off everything works normally. Any ideas? I was thinking my headlight switch may be going bad. It's a 90 Jimmy.

I suppose it could be the switch, but I'd also wonder if it's not a ground issue.
If you can get at them, what happens if you unplug the headlights and try? Removing that load (the only difference in your problem) should indicate a switch vs. wiring issue, IF it's a ground problem.
At least in my thinking.
