Abstract: The present invention relates to a full functioning service vehicle safety bar and sign assembly. A light system that utilizes a wiring harness assembly equipped with flashing directional arrows (<<<), the word SLOW or a combination of both. This light bar is mounted to a traveling device that allows the light bar to be extended beyond the parameters of its own frame to either the drivers side or the passengers side of the vehicle to which it is mounted. The unit can be mounted to the vehicle permanently or via a dual mount hitch and receiver system (i.e. the hitch can be mounted just inside the rear wheel wells where the under frame allows). The hitch and receiver system is comprised of dual female receptacles mounted to the vehicles frame inside the wheel wells where body type allows with male tongs fitting snugly into the receptacles secured with a locking device.
