The light guide body has a light entry area through which light from the light source can be coupled into the light guide body. The light guide body has at least a first light exit area for the back-up light and a second light exit area for the light for illuminating the ground region, wherein the first and the second light exit areas may overlap.

A light bar has a circuit board positioned within a housing and having a plurality of light emitting diodes (LEDs) or a thin-film-transistor liquid-crystal display (TFT LCD) is configured to transmit light. The housing has wiring electrically connected to a controller. The controller is configured to receive signals from the electrical system of the vehicle, interpret the signals received from the electrical system of the vehicle, and in response automatically control illumination of independently controllable segments of the vehicle light bar. The controller is initially programmed to perform specific function(s) and/or strobe according to specific patterns and is thereafter at least partially restricted from being reprogrammed by a user to serve other function(s), either by restricting the emission of light in at least one color and/or preventing specific strobing pattern(s).

A lighting system of a trailer. A rear end of the trailer includes a top edge, a bottom edge opposite the top edge, and side edges. At least one marker light is coupled to the top edge of the rear end of the trailer. The marker light is electrically coupled to an electrical system of a truck so that the marker light is activated when the truck is engaged in reverse.
