Product Description
Warning alarms are installed on vehicles and equipment to alert pedestrians, workers, and other nearby personnel to the vehicle's operation. They are often used in public transportation, construction machinery, garbage trucks, delivery trucks, and other vehicles and equipment that may be dangerous to pedestrians or workers. When the vehicle is reversed or the door is opened, the alarm usually emits a loud beep or voice sound, which is a warning signal to alert people who may be walking or working nearby.
