Progressive brake light apparatus

The progressive brake light apparatus sequentially lights three separate brake lights via hydraulic pressure sensing of the brake system between the master cylinder and the rear brakes. The apparatus provides a brake light assembly with the three distinctly different light sources disposed within, each of different size and different color, the brightest and largest being disposed at the top of the brake light assembly and the smallest and dimmest at the bottom of the brake light assembly. The apparatus thereby provides signal to trailing vehicles of the intensity of braking force applied, and therefore with a distinct signal of only initial brake pressure, versus average stopping, versus intense braking.
