This is for all E93 pre-lci. Apparently once one of the lights in the outer taillights go out you have to replace the whole socket board. Took me a while to find the PN's so here they are.
Left taillight bulb socket - PN: 63217178383
Right taillight bulb socket - PN: 63217178384
Currently on ECS they are selling for about $32 each that includes bulbs.
Hope this helps
