Abstract:
1. An automotive brake lighting system comprising: a brake assembly coupled to a brake pedal; a brake light including first and second light sources; a sensor to sense a level of an operating condition associated with a motor vehicle for illuminating said brake light; a controller configured to monitor information provided by the sensor for electronically controlling the automotive brake lighting system; and a memory coupled to the controller, the memory to store power control information for providing braking indications over a range of at least two different visual indications having a varying warning light pattern corresponding to at least one of sensed braking inputs during the actuation of the brake pedal or braking inputs associated with the brake assembly, the controller, in response to the level of the operating condition, to selectively power either one of the first light source or the second light source or both of the first and second light sources at substantially the same time based on the monitored information and the stored power control information, wherein the power control information incorporates a desired calibration according to which each of the braking indications as a function of braking rate of the motor vehicle is calibrated for a given level of the operating condition such that the at least different visual indications having a predefined relative difference on a particular scale over the range.
