    My 1 ton dump has a switch attached to a bracket welded to the truck frame. It is located on the drivers side just in back of the cab. When the dump body is completely down, that switch is activated by an adjustment bolt attached to the dump body and turns off the light.

    Maybe I misunderstood. Warning light like as in one in the cab to tell you the light is up? Or warning light as in a amber light on the bed?

    If it's not some goofy switch, I would say that when you raise the bed your wiring gets moved around a bit and I wonder if it's a bad spot in the wire at the hinge point in the bed.

    Kinda like a set of headphones where the wire at the jack wears out and you loose sound to the ear pieces.

    i should have explained better...it's a red light on my dash (used to be an IL DOT truck) it warns when the bed is at a specific angle (don't remember)

    it should have a switch something similar to this located toward the front of the dump frame if not this it should have a round knob looking thing in the same area

    This is the switch. It is usually mounted horizontally. The actuator (pointing up in this photo) is a spring (similar to a door stop), and it is pushed down by a piece of metal that extrudes down from the bottom of the dump bed. It can esily tested with a continuity tester. If you have power on both terminals than you probably need a new bulb.

    don't know about your state, but in NY DOT cops will write you if it does not work (to many people hitting bridges)

    I assume it's the same in all 50 states. I know it's the same in CA, & CO.
