Wore out three sets of tires already!
That is a vintage extremely clean and fully modified horn. It has a self-contained electric horn, battery pack, heavy duty metal toggle switch, and with the press of a button plays the classic la cucaracha Roach Coach horn. When the AA batteries die, simply pop the dust cap off for easy access. You have never seen anything like this and never will again since it's completely unique and one of a kind. Mounts easily to your bicycle with the custom clamp. If you want to see how it works, you have to buy it. Free United States shipping.
