My rear tail light on the drivers side isn't working. It blinks when I flip the signal lever, it works when I push the brake pedal, but if I just turn on the lights, nothing. I replaced the bulb, just to see if that would fix it, still nothing. All other lights are working. Have no idea what it could be. And ideas? Thanks in advance.

I forgot to add that it's an 2005 Dakota.

 

 

If the socket was bad, wouldn't that keep the light from working entirely? It's still working for signal and brakes.

 

 

I checked on the socket. The problem is the bulb does not fit into the socket tightly enough. I pushed on the bulb to make sure it was properly seated, and it came on. But when I reinserted the entire light assembly, then checked it again just to make sure, it wouldn't come on. But, if I give the thing a whack with my hand, it comes on. The bulb in it is a 3057. The bulb on the passenger side is a 3057K. Would that be the problem?
