Universal Backup Warning Alarms for Fleet and Heavy Trucks

At Rostra Accessories we are excited to offer two all-new heavy-duty safety products designed to alert pedestrians and other nearby drivers that a vehicle or piece of heavy equipment is in reverse motion. Available for immediate shipment, universal backup alarm part numbers 250-322BUA and 250-326BUA are discrete devices with 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.
