Ken, I puzzled over this, knowing fuse 15 and 16 were those two you speak of, but went fuzzy-eyed trying to trace the strange interconnection with the headlight switch as micrographed in the Bentley's most soiled pages. There's something to it, it seems, such as not to discount the relation between the tail light complaint coincidentally with the single side headlight problem. Otherwise, if my daughter said this I'd ask her to take a deep breath, count to ten and check the lights again for her flummoxed father. I'm eager to hear the rest of the story. Like maybe I forgot to fully seat the BFW sensor...nah...parking lights too.
