Signalling device with stop and position functions using a light guide and generating a 3D effect

The module (2) has a reflector (10) provided with a reflecting surface. A screen (12) is arranged in front of the reflector. The reflector, the screen and radiating units e.g. light guide (4) and LED (6), are arranged in a manner such that a first part of light rays emitted by the radiating units reaches a semi-reflective zone (16) of the screen. The semi-reflective zone is arranged with respect to the radiating units such that a second part of the light rays emitted by the radiating units does not reach the semi-reflective zone.
