A brake warning system is attachable to a first vehicle and for warning a second vehicle of an anticipated first vehicle braking. The system includes a vacuum or electrical switch operably connected to the first vehicle engine vacuum system and further includes a mechanism for monitoring a vacuum pressure fluctuation thereof. The vacuum switch sends a plurality of signals corresponding to accelerating and non-accelerating modes of the first vehicle and has a flasher light switch operably connected to it for receiving the plurality of signals therefrom for indicating when an accelerator pedal is released. The light switch is operably connected to the first vehicle brake light and flashes during an interval defined after an accelerator pedal is released and before the brake pedal is engaged.
