ABSTRACT:
An auxiliary light module for vehicles, giving "battery back-up" provisions, particularly useful for "semi" vehicles in which the pulling tractor electrically energizes the light systems of the pulled trailer by a connector strap or harness for interconnecting the tractor's output jack and the trailer's input jack; and the module provides a device conveniently connectable to both the tractor and trailer by jacking to the jacks now used by the jacks of such connector strap or harness. The module includes a battery, a switch, and circuitry for providing the electrical energization of the trailer's running lights and tail lights when the semi is stopped, and whether or not the tractor remains connected to the trailer, providing safety of the warning lights being lit, avoiding drain on the tractor's own battery, etc.
