For people that are running two aero brake levers with with only one of them used for the brake and the other being used just for the hand position in the hoods - do you connect anything to that dummy lever?

Parachute? Bell? Air horn? Strobe light? Spraypaint? Jet engine?

Seems like this has a lot of potential, kinda like the "what do I put on the shifter bosses on my conversion frame" question.
