While removing the front headlight nacelle on my '07 R1200RT, I found a part on the garage floor and have no clue as to where it goes! It appears to be a vent tube, for lack of a better description. There are two, identical to this third one that I found, on the rear of the headlight assembly (forgot to take a picture before reassembling), about 1/4" from the side parking light bulbs, one on each side. I suspect they are "breather hole covers" to help prevent condensation inside the clear housing for the 5 lights: 2 parking, 2 headlights, 1 high-beam. It's made of soft rubber, is hollow.
But where does this third one belong?!
