Abstract
The invention relates to an installation for signalling the deceleration of a motor vehicle. It comprises a signal lamp having an illuminating area divided into luminous sections, each equipped with its own light source, and means for controlling the lighting of a number of light sources which increases with the deceleration of the vehicle. The luminous intensity of the illuminating area remains substantially constant whatever the number of lighting sections lit. This constant intensity can be obtained by supplying the light sources with substantially constant power. The means for controlling the lighting of the light sources comprise a deceleration sensor and connection means which selectively link the light sources to an electrical-energy source as a function of an output signal from the sensor.
