“When I press on the horn people have to think ‘The world goes under’ ” Quote Homer J. Simpson, automotive engineer After I am constantly taken the lead, or I fear in other dangerous situations around my life and can only make me feel quite quietly with the original electric horn I want to make something loud now. According to § 55 (2) StVZO my horn is allowed to “emittieren” at 7 meters distance 105 dB(A). I want to use that now fully. Now we have an air pressure tank in the rear, it would be the easiest thing if I put a magnetic valve on it as soon as the horn button is pressed. So I only pump the horn and the valve. If it’s too loud still a pressure reducer. Does anyone already have something in the direction? Does the air travel unit suck when you turn some compressed air out of the tank in the stern? Or does the compressor just pump again brav after that? There are 8 bar on it, not true? (I at least have read it) I know what I need to lower it more often after the humpe is silently after I have to say something
