Zusammenfassung:	The utility model relates to a car speed reduction signalling device, comprising a vacuum tube, a vacuum auto-control circuit switch and a speed reduction warning circuit. When the speed of the car is reduced, the restrictor is closed, the vacuum is generated in the lower part of the throat restrictor of the carburettor, the vacuum auto-control circuit switch is sucked to move through the vacuum, the speed reduction warning circuit is switched on, and the signal lamp flashes to show that the speed of the car is in reduction. The device is in favor of the safety and the energy conservation, especially in the high speed running. The device can make use of the existing brake lamp on the car to make speed reduction warning lamp, which is easy to manufacture and convenient to install.
