Rear Bulb Out Nag Message

Rear Bulb Out Nag Message
One of the things I'm chasing down on my '99 XK8 is the Rear Bulb Out nag message. When I bought the car I had a handful of bulbs that were indeed dead. I replaced the ones that were dead with brand new ones (in pairs of course!) and I still get the message.
I've searched the forums and read a ton of pages on what could cause this. My question is this:
What does the bulb I highlighted in the picture do? No matter what I never see these lights illuminated on either side. Wondering if that's my problem there... See pic for reference.

As for the ground wire - it looks as though a stray blue wire comes off he harness and down into the carpet. Both harnesses have this. I haven't traced them back but m assuming these are he ground wires.

MRomanik - again, thanks for the PDF. Do you have something that corresponds to this PDF which shows the type of bulbs that are proper for our tail lights? I ask because I'm finding inconsistencies between different bulb vendors. Also, I found 2 different types of light bulbs installed in my housing. Both lit and functioned but they were different types.
According to Sylvania this is what our cars call for:
Back up light Part Number:7506
License plate Part Number:2825
Parking light Part Number:2825
Rear turn signal Part Number:7507
Stop light Part Number:7506
Tail light Part Number:5007
At the moment I have a collection of various bulbs installed from various vendors (OEM, Sylvania, GE, etc...). I'm considering yanking them all out and buying all new bulbs, start from scratch.

Just came back from Autozone and picked up new bulbs for the entire collection of sockets back there. Changed each one and tested them accordingly. They all light up perfectly as they should. However, I'm still getting the Rear Bulb Out message. :-( My third brake light is working fine as do the license plate and rear side bumper lights.
At this point I know my bulbs are now NOT the cause of this as it is something deeper. On both lamp clusters I have this blue wire that the P.O. spliced into the harness. It's cut into the second to last wire which I believe is red. The blue wire runs under the trim panel and to god knows where. I haven't had time to see where this goes or what it actually achieves (if anything).
Any ideas at this point are VERY welcome! Thanks again guys.

It would be connected to terminal 6 in the Right Side connector and Terminal 2 in the Left Side connector.
There are separate feed wires for the Left and Right Side units each going to a different Lamp-Out connection on the Lamp Control Module.
I think that one of the Tail Lamps was out (with a good bulb in both) and someone wired a Blue Wire from the Left Side to the Right Side, to make both lights work.
The wire going to the Lamp Control Module (The normal feed wire for that side) is open circuit and that is detected by the module as a bad bulb.
The Blue wire can be removed to indicate which (Normal) feed circuit is open.
It could be a open circuit wire or a bad Lamp Control Module.
