rear running light not working on 2003 Volkswagen Beetle

i have a 03 vw beetle and when i turn the head lights on the the tail lights should come on, the tail light on the driver side dose but the one on the other side dose not, i tested it to see if it had power and it didn't, any idea why it wouldn't have power only on one side, also the brake lights work, and i put new bulbs, any help would be nice thanks

Hard to say without looking at the vehicle, but its common for the bulb socket to fail. They are easy to replace and most dealers stock the socket.
