A self-contained illuminated sign for mounting on a vehicle is disclosed. The sign includes a front panel, a rear panel situated opposite and substantially parallel to the front panel in spaced relation therefrom to define a space therebetween, and a light source comprising a plurality of LEDs. The light source is positioned between the front and rear panels and is configured to emit light that emanates from the front panel. The front panel is thus backlit to display indicia. A system for supporting a self-contained illuminated sign on a vehicle is also disclosed. The system includes the sign and a separate mounting frame mountable on a vehicle. The mounting frame is configured to removably receive the sign and, when the sign is received in the mounting frame, to surround a perimeter of the sign while permitting visibility of the front display area. Related methods are also disclosed.

A heated light enclosure having an adaptable heating system is provided with a controlled heating system to deliver enough heat to a lens on a lamp assembly to remove snow, frost, and/or condensation without overheating the lens. By heating the lens using a combination of one or more of PTC heaters, heat sinks and heat pipes, accumulation of snow, ice, or vapor is mitigated or eliminated from a surface of the lens, thereby enabling light to transmit through the lens. Applications include lamps and bulbs on conveyance devices, including vehicles, boats, planes, and trains, as well as sedentary structures, such as lamp posts, street lights, railroad crossing markers and lights, and airport ground and runway lighting systems.

A cover unit for selectively covering an opening in a structure, including: at least a first cover element having a first axial end coupled to a first driving mechanism, and a second axial end coupled to a second driving mechanism; the first driving mechanism and the second driving mechanism configured to move the first cover element between a closed position and an opened position; each including: an arm configured to be rotatively coupled to the structure, at least one drive unit configured to drive a movement of the arm, and a joint configured to couple the arm to the axial end of the first cover element, the joint configured to allow a two-axis rotation and one linear axis movement, wherein the joint is configured to allow the first axial end and the second axial end of the first cover element to be moved differently during an opening movement and/or a closing movement.

An illuminated vehicle sign comprises a receptacle having an internal cavity with a light reflective internal surface. A cover over an end of the receptacle comprises one or more orifices opening into the internal cavity from an outside of the receptacle. The orifices are dimensioned and/or relatively arranged in accordance with one or more markings or alphanumeric characters. The orifices provide for ingress of air into the internal cavity from the outside of the receptacle and for emission of light from the internal cavity. A vent in the receptacle is positioned relative to the orifices to provide for egress of the air from the internal cavity. A light source is disposed within the receptacle to emit the light through the internal cavity and out of the orifices. An apertured screen is disposed inside of the internal cavity that is spaced apart from the cover.

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.

A light system having: (a) a plurality of light sources connected to a vehicle and creating light that radiates away from the vehicle so that the light substantially surrounds the vehicle; and (b) one or more sensors that detect light from another light source; and wherein one or more of the plurality of light sources are turned off in a direction of the another light source while some of the plurality of light sources remain on so that a tunnel having a reduction or absence of light is formed in the direction of the another light source between the plurality of light sources that remain on.

An apparatus for defrosting a vehicle light comprises a frame, a heating element connected to at least a portion of an internal facing surface of the frame, an attachment mechanism, and an electrical communication connection electrically connected between the heating element and a power source. The heating element may be configured to generate heat in the direction of the vehicle light, thereby melting snow, ice, or frost buildup on or in the vehicle light.

A tint film for application to a target surface, such as a headlight, includes a release liner, an adhesive layer, an at least partially transparent cast layer, and a tint layer. The tint layer is provided as an at least partially light-transparent layer, which may be printed upon the at least partially transparent layer using an ink-jet printing process. In addition, the adhesive layer is configured to have low-tack, so as to facilitate the ease in which the tint film is applied. In some cases, the at least partially transparent layer and the at least partially light-transparent tint layer may be formed together as a composite layer in a casting process.
