Abstract
Abstract A portable, heavy duty emerency power pack for hooking up to the lighting system of a vehicle trailer, such as a semi-trailer, camper, mobile home or the like, for the purpose of flashing all or some of the trailer lights on and off while the trailer is unhitched on the side of a road so as to warn passing motorists of its presence. In a preferred embodiment, the device includes a pair of heavy duty batteries connected in parallel, an on-off switch, a flasher, and a heavy duty case for housing these components. A cable extends from the case and is terminated by an adapter plug for connecting to a mating socket on the vehicle trailer. The case also preferably includes a carrying handle which is operatively connected to means for securing and locking the case to the trailer. The case further includes a lid having a lock device for securing the contents thereof against tampering. On the outside walls of the case may be mounted one or more light reflectors, illuminating work lights, flashing warning lights or the like. Auxiliary warning lights may also be strung from a special connector on the case, and alternate embodiments include the provision of a light-sensitive switch for deactivating the unit during daylight, and an alarm circuit connected to the doors of the trailer for sounding an alarm in the event of unauthorized entry.
