A lamp control system for vehicles includes a rail provided on a roof of a vehicle and configured to extend in a longitudinal direction, a lamp module slidably connected to the rail to slide in a direction of extension of the rail, and including lamps configured to emit light to an interior of the vehicle, a sensing unit configured to detect the number of passengers riding in the vehicle, positions of the passengers, or a position of cargo loaded in the vehicle, and a controller electrically connected to the lamp module and the sensing unit and configured to control operation of the lamp module based on the number and the positions of the passengers or the position of the loaded cargo, detected by the sensing unit.

An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal.

A trim component is provided. The trim component may include a trim panel, a backing layer, and at least one light pipe. The trim panel may have tapered side walls that extend from an inner portion of the panel and terminate at an edge to define a moonroof opening. The backing layer may wrap around the edge to define a trim ring. The trim panel may include integrated carriers that may project away from the panel and around the trim ring. The at least one light pipe may be disposed within the integrated carriers.

An illuminable vehicle interior assembly such as safety belt buckle assembly is provided. An illumination module includes a substrate, a light source supported on the substrate to emit incoherent visible light rays through a light emitting surface of the light source and a driver supported on the substrate to controllably supply electrical power to the light source based on a command signal from a remote electronic control unit over a vehicle bus. A lens is molded in a molding process to have a light transmissive output surface and a light transmissive input surface aligned with the light source. The lens gathers and receives the light rays at the input surface and redirects gathered light rays to the output surface to generate light in a pattern of substantially uniform intensity into a passenger compartment of a vehicle.
