A lamp for a vehicle or other object that includes multiple functions. In one aspect, the lamp includes a first circuit for emitting a first color light (such as red light), and at least a second circuit for emitting a second color of light (such as amber light). In another aspect, the lamp optionally includes a microcontroller that may be programmed to control the activation of the different colored lamp circuits based on lamp location information, and based on an operating mode.

A mounting bracket for attaching an electrical coupling of trailer light electrical system to the hitch receiver tube of a towing vehicle is described. The mounting bracket removably attaches to the receiver tube such that the bracket does not interfere with the tube opening and has a electrical coupling mount flange that is located sideways from the receiver tube in a cantilever like fashion.

A safety lighting system for use with trailers is described herein. In some embodiments, the trailer lighting system comprises a sensor, a controller, and safety lights. The safety lighting system may be used for illuminating trailers while being towed, for example, in shipping yards, construction yards, and shipping and receiving docks. The safety lighting system may be activated upon connection of a pneumatic system with a spotting tractor and deactivated upon establishing an electrical connection from a tractor to the trailer.

A wireless lighting system used with demountable equipment, including truck-mounted forklifts (TMFL). The system includes a transmitter installed in a lighting harness or trailer lighting socket on a transporting vehicle. When the transporting vehicle's notification lights or signals (turn signals, tail lights, brake lights, clearance lights, reverse lights) are activated, a wireless signal is transmitted to a wireless receiver located on the TMFL, and a corresponding light or lights are activated on the TMFL. The system utilizes the power source of the TMFL to power the notification lights of the TMFL while being transported. Further, when the forklift is dismounted and in operation, the wireless lighting system is disabled until the forklift is returned to the transport position on the transport vehicle. This prevents actuation of the lights on the forklift unless the forklift is on the transport vehicle.

A trailer lighting activation system includes a vehicle light sensor, an ambient light sensor, and a microcontroller. The vehicle light sensor is removably attached to a towing vehicle light to detect a light output of the towing vehicle light, and to provide a vehicle light sensor output signal in response to the light output of the towing vehicle light. The ambient light sensor can detect an ambient light level and provide an output signal in response to the ambient light level. The microcontroller is coupled to the vehicle light sensor output and to the ambient light sensor and has an output for energizing a trailer light in response to the ambient light sensor output signal and the vehicle light sensor output signal. An overcurrent monitor is coupled to the trailer light and to monitor current drawn by the trailer lighting activation system.

A semitrailer rear lighting device for enhancing safety of a semitrailer hauling an oversized load includes a plurality of brackets, a pair of bars, and an indicator. Each bracket is mountable to a respective opposed side of a semitrailer so that at least two brackets are mounted to each opposed side. Each bar is slidably engaged to the brackets positioned on a respective opposed side of the semitrailer. The bars are selectively extensible from a rear of the semitrailer to position a terminus of the pair of bars past an end of an oversized load that extends past the rear of the semitrailer. The indicator is engaged to the terminus of the pair of bars. The indicator indicates to a trailing motorist one or more of the rear of the semitrailer, the end of the oversized load, a braking action of the semitrailer, or a turning of the semitrailer.

A removable light for a towed vehicle includes a housing with a low profile shape, an anchor, a safety tether strap, and lens protection features.

An adapter for use with components of a truck trailer. The adapter may include multiple input terminals corresponding with multiple terminals of a trailer component socket of a trailer, and multiple output terminals configured to electrically connect with corresponding input terminals of a trailer component. The adapter may also include an adapter circuit configured to electrically connect at least four of the input terminals with at least four of the multiple output terminals. The multiple output terminals may include at least two mode selection output terminals configured to provide a mode selection to the trailer component, and the trailer component optionally includes control logic configured to activate and deactivate the trailer component according to the mode selection.

There is provided a first vehicle shaped to be received on a cargo bed of a second vehicle. The first vehicle includes at least one rear light. The first vehicle includes a wiring harness coupled to the rear light of the first vehicle. The wiring harness is connectable to at least one electrically-powered rear light of the second vehicle so as to be powered therefrom and to function in concert therewith.
