Mechanical Backup Alarm Bell, No voltage/power required. Mounts on a wheel hub and has 2 internal hammers that rotate around as the vehicle wheel turns to provide the bell ring when backing the vehicle (either version can be used for forward motion sound as opposed to backing sound), 6" diameter (BKA), or choose 8" diameter version with 4 internal hammers sounding as the wheel turns (4 hammer--CVA). The BKA is intended for small to medium size vehicles--no mounting hardware is included due to the wide range of mounting configurations. The CVA version is ideal for larger wheel hubs and includes mounting hardware for adapting to various hub sizes. See the Instructions link for specifics about each model (BKA and CVA) including the optional CVAUMP
Both are ideal for applications where vehicle power is unavailable, or when switches are difficult to install.
