is the bulb and connecter one unit?. Have one bulb that is burnt out and I can't get the damaged bulb out ut of the socket, I also see that the assembly just un plugs. once you remove the bulb from the fog light cassing.

 

The bulb comes out by simply twisting it counter-clockwise 1/4 turn. The harness / connector slips off by releasing the tab. (Remove the electrical connection first.) Be sure not to touch the glass part of the new bulb with your fingers. The oil from you skin will shorten the life of the bulb.
