Not to be argumentative, but You are decreasing the potential of the horn by at least 50%-unless you need to warn drivers behind you. Assuming rain could get to the top of the vertical trumpet, All you would need to do is HONK IT before you put it away, to get rid of any water or particles. I sold my entire Bad Boy because it was to bulky, for about $15.to a forum member, & don't miss it.
My FIAMM, is nearly as loud, faces forward, doesn't stick out, & no relay is needed. Sorry to disagree.
