I got the License Plate Bulb warning .Replaced the bulb but no light,warning remained. I tried the bulb in the functioning receptacle and it lit then i swapped receptacles . The bulb holder which was not lighting when switched to the plug which was lighting and with the tested good bulb lit there so both bulb receptacles are functioning. Where is the problem. No other lights are out and i see the plate bulb wires splice into the trunk lights harness. Can i buy the plug cut off with some wire length from somewhere like Euro Depot and splice that in or will i find the problem elsewhere? The metal holder parts were caked with green oxidation and the bulb was black yet it as i said did work when swapped to the other side..
