An elongated aircraft cabin light for illuminating a passenger cabin of an aircraft from a ceiling of the passenger cabin comprises: a row arrangement of a plurality of light modules, extending along a longitudinal direction (L) of the elongated aircraft cabin light. Each of the plurality of light modules comprises at least one light source. The plurality of light modules include a plurality of intermediate light modules and, on at least one end of the row arrangement, an end light module. Each of the plurality of intermediate light modules is configured for emitting a downward light output and at least one lateral light output towards at least one lateral side.

An automatic aircraft lighting control system can include a control module. The control module can be configured to receive imaging data from one or more cameras operatively associated with the aircraft and automatically control external aircraft lights based on the imaging data.

A lighting system and assembly comprising a controller in operable communication with a light unit. The controller is configured to apply a lighting condition using the light unit for a target light color below an upper level of NVIS radiance while controlling a Melanopic-Photopic (M/P) ratio associated with the target light color, and also determine a color mixing for producing NVIS Green A light and NVIS white light for a plurality of levels of NVIS radiance which are less than a maximum NVIS radiance level for a set of M/P ratio values at an upper allowable limit and a set of M/P ratio values at a lower limit.

In one instance, a light weight safety arm is coupled to and extends beyond a stop sign coupled to a motor-driven rotatable mount on an exterior side of a school bus. In another instance, a school bus safety device is disclosed that includes a stop sign portion, an arm portion, and a mounting portion. The arm portion, stop sign portion and mounting portion are cut out together as one piece from a single sheet of material. Other embodiments and variations are further disclosed.

A method performed by an in-vehicle apparatus includes setting, in video captured by an imager, a first area and a second area in front of a door in an interior of a vehicle, extracting one or more passengers and one or more objects from the video using an image analysis technique, and causing an opening and closing operation of the door to stop, upon detecting, in the video, a passenger present in the first area and/or an object present in the second area.

A visual alert assembly for use with a school bus having a rear shell seating one or more PC boards integrating illuminating elements. A forward facing outer perimeter mounting surface of the shell includes an adhesive adapted to mount the assembly to a glass associated with any of a forward windshield or rear window of the vehicle so that the illuminating elements are visible through the glass. Each of external power and control inputs extending through the rear shell and communicates with the PC boards for operating the illuminating elements according to any of intensity, color or pattern in response to a change in a travel condition of the vehicle.
