Most modern streetcars, trams and trolley cars including low-floor vehicles around the world also employ horns or whistles as a secondary auditory warning signal in addition to the gong/bell which either use the sound of air horns or electric automobile car horns. A klaxon is a type of an electromechanical horn or alerting device. Mainly used on cars, trains and ships, it produces an easily identifiable sound, often transcribed onomatopoeiacally in English as "awooga". Like most mechanical horns, it has largely been replaced by solid-state electronic alarms, though the memorable tone has persisted. Klaxon was originally a brand name. These mounts are circular, so you’ll need circular handlebars to attach the Hornit or a circular bike frame. The Moflash Company discontinued the Klaxet hooter in 2013, but continued to produce the A1 hooter, the only original Klaxon left in production.

that are both louder and lower in frequency than motor vehicle horns. Operated by compressed air from the train's air brake system, their sound level is 146–175dB. In the United States, train horns are required to have a minimum sound level of 96dB and a maximum sound level of 110dB at 100ft (30m) in front of the train.Bloom is a white residue that sometimes forms on rubber. Our bulbs are infused with a "sacrificial" stabilizing wax that protects rubber against the degrading effects of ozone leading to dry rot. Incidentally, you can protect the bulb from dry rot by simply honking the horn. That's because squeezing the bulb flexes the rubber which triggers the stabilizing additives. Bloom indicates the wax is working. Surface bloom can be removed using detergent, olive oil, or a commercial rubber protectant.

The Hornit, however, is battery-powered, and with regular use (6 horn blasts per day), the two AAA batteries should last a year before needing to be replaced.
