The invention discloses an automotive brake signal device capable of changing the flashing frequency of brake lamps with braking force. The automotive brake signal device comprises a power supply, a brake switch, the brake lamps and a flasher circuit, wherein the flasher circuit is connected with the brake switch and the brake lamps in series; the brake switch comprises a slide rheostat; a sliding sheet control lever of the slide rheostat is connected with a brake pedal; when the brake pedal is released, the resistance value of the slide rheostat is the maximum value; when the brake pedal is stressed, the resistance of the slide rheostat in the circuit decreases with the increase of braking force. According to the automotive brake signal device, when the automotive braking force is small, the brake lamps emit dim light, the flashing frequency cycle is long, and the visual effect is gentle; when emergency braking is started, the brightness of the brake lamps is increased, and the flashing frequency is increased, so that the effects of warning automobiles behind and pedestrians behind are achieved.
