Abstract
A light unit or indicating device for a vehicle (.e.g., a vehicle lighting unit, a vehicle indicating unit, reversing radars and other systems) has a shell, a light contained in the shell, and an electronics card mechanically associated with the shell. The electronics card is connected an electrical power supply and to a multiplexed bus of an on-board network. The card has a controller for the light that allows exchange of commands and information on status of the light unit over the multiplexed bus, and also has an internal bus connected to the controller and the light that allows exchange between them of commands generated by the controller and of the status information of the light unit. The unit may also have an ancillary component for implementing ancillary facilities such as light beam adaptation or automatic adjustment of the orientation of the light beam.
