1 Answer
1, You did put the new bulb in and not the old one? Also check the fuse. 2, Did you pull on the wires to remove the socket? In which case you could have broken a connection 3, The new bulb could be broken already, take the bulb from the working side and try it on the side that does not work since you know this bulb is good. 4. Test the wires and test the socket to make sure the power is coming through.
