The 97dB alarm and LED lights combine sound and visibility for people behind the vehicle. Its standard 7-way RV blade socket fit supports compatible trucks, trailers, and RVs, making the plug-in approach relevant to users who want a socket-connected unit. Confirm the vehicle has the specified socket type before choosing it.
