I had a tune up done to the car and when the taillight was still out i noticed the socket was broken if anyone has one my email is perez266@netzero.com

 

Never ever have I seen the tail light socket when doing any kind of tune up, please explain.
On the socket there will be a number moulded in it, what is it please?

 

Bet someone tried to force install a American brake light bulb into a European socket. The studs are spaced differently. Squirrel Crusher

 

The only identification is the >PA66< and CEMM. I tried to use one of the OEM replacements on ebay but they dont fit correctly and when i turn the headlights on its like my foot is always on the brake in the daytime its also brighter than the other side

 

Maxichon found that PA66 was the recycle logo showing what type of plastic it was, fiber reinforced plastic of some type.
CEMM(?)
There has to be a part number on it somewhere I am sure, inside maybe?
A post some time back by (?) said the similar part on a SLK was on recall because oh heat damage over time.

 

i found P21/5W could this be it?

 

That is the bulb number, this is the socket I think, check it with the one you have. CLICK
Google P21/5W socket.

 

this is the exact one i found on ebay not a direct fit but i got it in there just it seems to only from either off or both filaments are lighting up i'm actually going to try to rewire maybe its just wire wrong
