Provided is a power supply device for a lighting device for a vehicle composed of a plurality of unit lighting modules which is easy to install and disassemble due to excellent assembly capabilities, and which stably supplies power with excellent connection stability. In the power supply device for supplying power to the lighting device for the vehicle composed of a plurality of unit lighting module, the power supply device includes: a connection rail member provided in each unit lighting module to supply power to a PCB of the unit lighting module; and a connection pin member electrically coupled to the connection rail member in a male and female manner to electrically connect two adjacent power supply modules to each other.

An apparatus includes an auxiliary light includes a housing defining a front opening, a light emitting in the housing, and a transparent cover is mounted over the front opening. A plurality of fins are mounted to the housing and extend rearwardly from the front opening. The housing defines a cavity of non-rectangular shape from the opening to a backwall of the cavity. A circuit board has a perimeter conforming to the non-rectangular shape. The circuit board may include cutouts for a plug through the backwall. A heat conducting pad, such as graphite is interposed between the circuit board and the backwall and may likewise conform to the non-rectangular shape.

An auxiliary lighting system for an auxiliary device and methods are provided. The auxiliary lighting system senses the operational state of various ones of the vehicle lights of the vehicle and operably controls the operational state of various auxiliary lights based on the operational state of one or more of the vehicle lights. The method includes controlling the auxiliary lighting system based on the operational state of the vehicle lights.

A structural unit for provision in the front end or in the tail end of a motor vehicle, wherein the structural unit comprises a support body and at least two environment sensing systems, wherein the environment sensing systems are received on the support body.

First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.

Provided is a lighting device to be installed in a vehicle, more particularly, a lighting device having a structure in which a plurality of unit lighting modules are installed on a bracket. Thus, the lighting device may allow users to select the size or shape of the lighting device, to replace or maintain only a unit lighting module where a problem occurs, and to implement various lighting patterns. The lighting device includes: a body; an LED module embedded in the body; the unit lighting module including a front cover being transparent and covering a front of the body; and the bracket on which the plurality of unit lighting modules are installed.

A working spotlight for a vehicle is provided, featuring a housing, a light source, and a light guide system for guiding working light generated by the light source in a predefined direction out of the housing and into a working area. In and/or on the housing, a means of generating a motif is arranged for projecting at least one motif onto a projection surface outside of the housing.

A lighting apparatus for connection with a trailer includes an elongated housing having an upper end and a lower end adapted for connection with a post, and at least one sidewall. A mounting assembly is connected with an upper portion of the elongated housing and a light is connected with the mounting assembly. The housing has an inner chamber for receiving a wire harness and/or power source for the light. When the elongated housing is connected with a trailer frame, the light faces a rear direction relative to the trailer and is operable to illuminate the area rear of the trailer.
