Retrieved January 20, 2011.Klaxons were first fitted to automobiles and bicycles in 1908. They were originally powered by six-volt dry cells, and from 1911 by rechargeable batteries. Later hand-powered versions were used as military evacuation alarms and factory sirens. They were also used as submarine dive and surface alarms beginning in the Second World War. The Tornado Car Horn by Marco is the loudest car horn you can buy at 151dB. This not only beats the competitors, it dominates them by a country mile. There is no additional power supply required and this car horn can fitted to all cars with a 12 volt electrical supply.

Owning a digital multimeter is really handy for installing components such as a horn. This device will help you find continuity within wires if you cannot seem to power up the horn.As you can see from the image below, they do become fairly corroded overtime.

Typical frequencies of a pair of horns of this design are 500Hz and 405–420Hz (approximately B 4 and G ♯ 4, minor third). Below is a list of the best loud car horn upgrades that are direct replacements and some of the loudest available. The Best Loud Car Horn Upgrades
