ABSTRACT:
A method and apparatus for warning a following vehicle when a vehicle in front applies its brakes are provided. At least one brake light of a vehicle illuminates during a braking process as the braking value increases in conformity with a present value of the braking value. After the value drops below the maximum value, the illumination continues for a retention time that is a function of the braking process, and after the conclusion of the retention time fades during a period of time that is a function of the braking process.
