It is for all rear lights, and the rear side markers, I could see a dead LED causing it.

When I picked up my Supra some of the bulbs were stock Toyota, lol. The first one I went to replace shattered from the pressure of my fingers and cut me pretty bad, I had to use a pair of pliers after that to loosen the bulb, did the same for another three bulbs. The third brake light was also out, literally, all I had there was two wires, lol, I still haven't gotten around to buying a socket for it. The weird thing is that after a few months of driving the warning light stayed off, and it hasn't came back on since.
