Whats the coolest 12volt thing you have on your vehicle or have instal

Mine is a train horn with the on board air and everything thats needed to make people get out of your way!
but only for fun (unless you make me really mad) , I have my regular horn still wired in.

I remember someone posting a vid of a guy with a train horn scaring the crap out of pedestrians.

If its not my part of town yeah maybe sometimes I do get that bus stop with about 20people If you seen the reactions people give you its hilarious when some tough guy punks walk out in traffic taking their time and hitting it they take off and scream.
