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 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 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.

A device for signaling a vehicle encumbrance, in particular a transverse encumbrance of said vehicle, in particular usable on agricultural and/or forestry machinery or for signaling a load protruding from said vehicle, comprising means for signaling the overall dimensions and means which connect said signaling means to the same vehicle. Said means which connect said signaling means to the same vehicle are adapted to support said signaling means in respective positions, in particular transversal with respect to the same vehicle, said positions being comprised between a maximum extension position and a minimum extension position with respect to said vehicle.

An apparatus connecting to a hitch of a vehicle. The apparatus includes a light emitting diode (LED) light stick mounted to the hitch of the vehicle via a hitch adapter. The hitch adapter configurably slides into a hitch mount of the 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 slow moving vehicle safety device for reducing accidents involving slow moving vehicles includes a housing, which defines an interior space and which is mountable to a rear end of a slow moving vehicle. A power module, a microprocessor, and a receiver are engaged to the housing and are positioned in the interior space. The power module and the receiver are operationally engaged to the microprocessor. The receiver is Global Positioning System enabled and receives coordinates and relays the coordinates to the microprocessor, which calculates a speed of the slow moving vehicle. A plurality of bulbs, which is engaged to a rear facing facet of the housing and is operationally engaged to the microprocessor, can selectively emit light of a variety of colors. The microprocessor is enabled to selectively actuate the bulbs to emit light of a respective color based on an associated speed of the slow moving vehicle.
