I'm shopping around, and am seeing lots of options for pre-facelift E53's....but not many for my 2005 post-facelift. They look like identical shapes externally - are they? And if so, are there other incompatibility issues regarding the wiring/connections inside?

Apologies - I know there are lots of threads about the wider LED upgrade topic already, but I'm struggling to find a clear answer to this specific question. I just need to be sure I buy the right thing before splashing the cash.

10 cents of solder will solve your problem. After replacing three tail light assemblies. I found the solder fix, applied it to a problematic tail light assembly. Problem solved. Put a dab of solder on the tail light housing where the bulb housing rests. The problem isn't corrosion it's poor contact which causes shorting that damages the connection. The solder provides a better, solid connection. Problem solved. Ten cents.
