Horns are an important part of golf carts, as they are used to alert other players and pedestrians of the cart's presence. Horns come in a variety of shapes and sizes, and can be powered by either 12-volt or 24-volt batteries. Most horns are made from durable plastic or metal, and some feature a waterproof design for added protection. Many horns also come with mounting hardware for easy installation on the golf cart. Finally, some horns even feature adjustable volume settings so you can choose the right sound level for your needs.
