I have an 03 cavalier and I need to replace the bulb. I guess i need some help because I am sure it is held on by some sort of clips. Any help would be appreciated.
 
Its just a 1/4 turn socket and the bulb is a 3057, but a 3157 will work.
 
 
Yeah i have the correct bulb already for it. I am talking about the black plastic part where the bulb goes into the taillight itself. I mean is there anyway to pull the thing out without having to remove the entire taillight? 
Thanks
 
Yea open the trunk and pull the liner back.
 
 
I know that much.....i am talking about after you pull back the liner and u are looking behind the taillight and there are what it looks to be a set up for 2 bulbs....there is a big one and a small one...the small one comes off with 2 little clips and that is what i am trying to look for on the bigger one but i cant get it to come off
 
So your trying to get the bulbs out of the socket?  Just pull.  There isnt any clips holding the big bulb to the socket.
 
 
^^^^sounds like hes trying to get the socket out of the taillight. i have an 01, so i dont know what clips you are talking about, but you should just have to twist the socket to unlock it.
 
All sockets mount into the taillights the same for 95+.  Thats why all taillights are interchangeable.  Changing a taillight bulb is very simple.  Twist and pull the socket and just pull the bulb out.(you might have to wiggle the bulb alittle).
Brandon, if you can post a pic of what your talking about i'll be able to help you more specifically then trying to guess at what your talking about.
