ABSTRACT:
A portable, lightweight and inexpensive emergency power pack to be hooked 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 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. The device includes a battery, an on-off switch, a flasher and an illuminating light. The case for supporting the battery and other components is made of a unitary, molded plastic piece, and includes a cylindrical housing on one side thereof that contains an adapter plug for connecting to a mating plug in the vehicle trailer. Auxiliary warning lights may also be strung from a special connector on the unit, while an alternate embodiment may be utilized in the shop to test the various electrical systems on the trailers.
