It was easy to install and has held up well to wear and tear. Requires 2 AAA batteries to operate. You have not been included. The black button is the horn button to activate the sound. Attaches separately to the steering wheel. The red button on top is the mode button, it changes the sound that is played when the black button is pressed. There are five different sounds to choose from. It's not a cheap little horn, but has a pretty powerful and very loud sound. Everyone should have one on their bike to alert others to their presence when needed. This will help you stay safe there.
