You are correct, that is the only brake light.  I have the bubble lenses
on mine, also.  But you see, to "normal" people trying to explain how this
setup works, its simpler to describe it as the 3rd brake light, even though
its really 1 of 1.  And everyone I'd talked to in my search for this
thing knew exactly what I was talking about.

However, I have seen a few later buses (still splits though) that have 
put one on the engine lids on.  I those cases, it truly is a 3rd brakelight.
