2006 Hyundai Tucson rear door lights work once in a while is there a switch

is that the latch itself that locks the door at bottom of rear door

now driver side tag lamp stopped working changed bulb still won't light

tag lights wont come on until you turn the headlights on,if lights are on,and still not working check fuses..and spray the switch not the latch on the doors.

headlight switch is on but still not lite even bought new bulbs again

look in owners manual for fuse locations,and check them if both tag lights are not working

all fuses ok only 1 tag light not lite driver side passenger side is lite

need to check the socket,make sure inside not corroded.loose,or broken wire.try moving the socket and wire around,see if the light comes on.you need a volt meter to check for power at that socket.is the socket metal or plastic,also just one wire on it?
