Truck back-up alarms are an easy way to keep everyone safe. Back-up alarms are discrete, have simple two-wire connections that power on automatically and output a loud tone when a driver shifts their vehicle into reverse, or manually through the use of an on / off toggle switch, to get the attention of anyone nearby.
