Headlight problem with our Peacekeeper

[Tnrobocop]

Peacekeeper at our department has an issue with it's headlights. They will work about half the time, then will go out and maybe come back on later. The weird thing is that some days they work great and other times not so much. Additionally when the lights go out, all of the other lights still work (i.e. running lights, turn signals, dash lights, etc.).

Any ideas?

Sounds like you likely have a bad ground somewhere in the system. Look around under the hood and find what grounds you can like to the motor and body and disconnect, thoroughly clean of rust and paint then reattach. Replace any rusted wires.
