A reflector unit may behave as a retroreflector to reflect light of a selected color. The reflector unit may comprise a first reflector having a first color, a second reflector having a second color, and a mask that either allows incoming light to reach the first reflector and not the second reflector or allows incoming light to reach the second reflector and not the first reflector. An active light unit may emit light of a particular color in response to receiving light. In this fashion, the active light unit may simulate the operation of a reflector. The reflector unit and the active light unit may operate on a bi-directional vehicle.

A directional illumination device for a vehicle external light comprises an array of light sources and an imaging waveguide comprising an input surface and a reflective end. Opposed guide surfaces are arranged to guide input light from the input surface to the reflective end and back along the waveguide after reflection at the reflective end, the waveguide being arranged to extract input light as it is guided back along the waveguide after reflection and to cause the extracted light to exit through the first guide surface. The reflective end has positive optical power in the direction laterally across the waveguide and the waveguide is arranged to direct the extracted light in respective output illumination directions distributed in a lateral direction in dependence on the input positions of the light sources in the direction laterally across the waveguide. A thin, high brightness and high efficiency controllable directional vehicle headlight is provided.

A retrofit trailer board system for vehicles is disclosed, including a trailer board carrying a plurality of signalling lights on a surface thereof, and a relaying control unit which is connected between the trailer board and a plurality of optical sensors. Each optical sensor is arranged for removable connection to the exterior surface of respective vehicle lights, each sensor being configured to issue a signal responsive to operation of a vehicle light.

An automatically deployed tripod for a vehicle includes a fixing frame formed as a housing having one open side surface, a folding frame having one side coupled to the fixing frame to be folded and inserted into the fixing frame or to be unfolded and protrude out of the fixing frame, and a driving part coupled to the interior of the fixing frame, to fix the folding frame into a folded state, and to release the fixing of the folding frame by an operation of a user and cause the folding frame into an unfolded state.

A customizable modular lamp is made up of an outer lens customized by known per se techniques, which covers a housing provided with at least one recess in which is mounted a customizable module consisting of a retro-reflective lens under which there is an inner customized lens personalized by known per se techniques, under which there is a printed circuit board with LEDs that is held in a holder fastened to a cover provided with at least one element for ventilation. During the daylight, personalization is visible on the outer customized lens. In the darkness anddepending on the recipient's requestwhen activating the lights for changing direction, position or braking, customization becomes evident by lighting inside the lamp, on the surface of the inner customized lens.

A method, device, and system embodying an auxiliary light assembly for providing auxiliary rear lighting for vehicles having standard hitches. The auxiliary light assembly may include an enclosure adapted to operatively associate with, by way of a hitch tab, the hitch receiver of a standard hitch so that the auxiliary light assembly can be attached to the vehicle without altering the vehicle. Adjacent to the hitch tab a mounting tab may be provided along the exterior of the main body of the auxiliary light assembly. The enclosure encapsulates one or more lighting units, thereby protecting them from debris and mud as well as forming a secure connection between the one or more lighting units and the standard hitch.

The present invention relates to an automatic light intensity control device for vehicle rear lamps in response to changes in visibility distance and its control method. To this end, the automatic light intensity control device for vehicle rear lamps of the present invention comprises: a visibility distance measurement unit that is mounted on a driving vehicle or installed in the vicinity of a driving road to measure a visibility distance of the road in real time; and a light intensity calculation and control unit that is mounted on the driving vehicle to calculate an appropriate light intensity using visibility distance information measured by the visibility distance measurement unit and then control the light intensity of rear lamps in real time.

A reflective substrate removably connected to at least a portion of at least one of a headlight and a tail light of a vehicle, the reflective substrate including a main body, including a reflective layer disposed on at least a portion of a first side of the main body to reflect an external light illuminated thereon and away therefrom in at least one angular direction toward at least one of a side, a top, and a bottom of the vehicle, and a transparent layer disposed on at least a portion of a second side of the main body opposite with respect to the first side to pass a beam of light from at least one of the headlight and the tail light through the transparent layer to the reflective layer, and a vehicle fastener disposed on at least a portion of the main body to removably connect the main body to at least one of the headlight and the tail light.

A system includes a housing, at least two lighting units, a lens, at least two fastening elements, and a protective optical element which covers the fastening elements of the lighting system. The lens and the housing are provided with at least two corresponding openings provided in a central area and configured to allow the positioning of the fastening elements. The lens has a frontal surface, comprising a central recessed area. Tubular elements oriented inwards to the lighting system extend and fit into the corresponding holes, when assembling the lens and the housing.
