Homogeneous system of rear lights for motor vehicle

The invention relates to a homogeneous rear signaling light system (101) of a vehicle, each lamp being adapted to be mounted in a rear corner of the vehicle having a body shell (C) and a flap (V) back working. This system includes two groups of light units for each taillight, a group of "cash" lights (1) and a group of "flap" Light (2) and a central member (22) control of light intensity emitted by the vehicle taillight. This member (22) distributes at least a light intensity of a duplicated manner between the two groups of tail lights (1; 2) corresponding to a light signal. The system (101) also comprises an opening sensor (21) of the flap (V) capable of transmitting an information signal opening / closing the flap (V) to the central member (22) control of light intensity which, in case of transmitting an opening signal is then able to provide each cash unit (1), a light intensity control signal increased with respect to the rated current corresponding to a duplicate component state (V) closed.
