A vehicle LED lighting outage detection circuit is disclosed for detecting a fault in the LED light and automatically increasing the power drawn from the light power supply in response to the fault. A complementary detection circuit is also disclosed for detecting the increased power draw and signaling a fault to an operator. The increased power draw can be selected to be in the form of a pulse that settles to a lower power draw state after a time to avoid excessive and wasteful power draw. The system can be mounted in a vehicle and, more particularly, to a semi-tractor truck.

Trailer lighting outage detection circuit

A vehicle LED lighting outage detection circuit is disclosed for detecting a fault in the LED light and automatically increasing the power drawn from the light power supply in response to the fault. A complementary detection circuit is also disclosed for detecting the increased power draw and signaling a fault to an operator. The increased power draw can be selected to be in the form of a pulse that settles to a lower power draw state after a time to avoid excessive and wasteful power draw. The system can be mounted in a vehicle and, more particularly, to a semi-tractor truck, or installed as a retrofit system into an existing semi-trailer system.

An electrical power supply device for a trailer lighting system behind a truck is disclosed. The trailer lighting system including at least two FMVSS 108 compliant LED stop-tail-turn lamps. The electrical power supply device has an outer casing including a terminal to be electrically attached to and become part of the trailer lighting system. There are a plurality of electrically conductive wires within the casing. At least one of the wires is selected from one or more of the group consisting of low copper usage wire. The device has an over-current protection device along at least one which breaks current flow through the one wire below at an amperage threshold less than 25 amperes.

Trailer wiring over-current protection

Lamp plugs are disclosed, in which single intensity marker lamps that are desired to be flashed can be connected to a lamp driver employing an exclusive OR (XOR) logic circuit. In one embodiment, the lamp plug is an overmolded subsystem that is installed between the lamp and the lamp driver and allows the installer to use existing wire harnesses. In some embodiments, the overmolded subsystem is installed under a standard lamp where a plug is typically plugged in; therefore staying on the vehicle and not needing to be replaced with the lamp. Other embodiments are disclosed.
