A vehicle having left and right lower rear brake lights and a Center High-Mounted Stop Light (CHMSL) flashes the CHMSL when the brakes are initially applied. The lower brake lights do not automatically flash. After a predetermined duration, the CHMSL remains continuously illuminated until the brakes are removed. In an effort to improve on the design referenced by U.S. Pat. No. 5,345,218, a micro-controller circuit is configured to be activated when brakes are applied. Once activated, internal embedded micro code produce a predetermined number cycles of an oscillating output signal that is responsible for causing the CHMSL to flash. After the numbers of cycles have been completed, the embedded micro code forces the output signal to remain in a state that causes the CHMSL to stay illuminated until the brakes have been removed.
