real lt tail light does not come on
Buy yourself a 12 volt needle test light. Remove bulb. Touch the test light to the bulb socket. If no power, there should be a power wire and a ground wire. Clean your ground. Retest for power at the socket. If still no power, poke the needle into the main power wire until you find where it will actually light up the test light. Cut your wire there and splice in a new wire from there to the socket. You will probably find the main power wire is broken or just corroded within the wire harness that runs along the frame.
