Normally it is always a gound issue. Take a separate wire and go to the frame and the ground wire or the grounding point on your light (exterior of the bulb holder) and see if it works. If it works, trace your ground wire(white if the wires are black and white- black if the wires or red and black) as it has lost ground at some point. If this does not work, check to see if you have 12v on the hot (black wire if white and black - red if red and black) wire. If you don't get 12 v on it, you need a multimeter, hook long wire to the plug up front, set the multi-meter on continuity, hook one probe to the wire going up front to the plug and the other to your hot wire at the light and check for continuity. If you don't have continuity there is a break in the wire. Time to trace it and see where the problem lies.
