The Hornit dB140 makes cycling on the road much safer. Recumbent riders and anyone looking to make themselves known on the road will want one. ?Weighing just 96 grams (with 2 AAA batteries installed!), this seriously loud horn has two modes for up to 140 decibels of sound to attract motorists' attention. Splash-proof case won't let a little rain stop you from making a big noise at the right time.
