The invention discloses a method for displaying low-speed running and the speed of an automobile by tail red lamps. After receiving driving and safe stopping which are output by an automobile key main switch by a driver or braking information output by a braking switch and automobile speed information sent by an automobile speed acquisition unit, a micro control processor processes the information to form tail red lamp control information and sends the tail red lamp control information to an intermittent controller; the intermittent controller is used for controlling the shining time length and the intermittent time length of the tail red lamps; shining of the tail red lamps is used for representing the low-speed running of the automobile, and the ratio of the shining time length to the intermittent time length of the tail red lamps is used for representing the driving speed of the automobile. A rear driver can see the tail red lamps clearly and understand whether the front automobile runs at the low speed as well as read the automobile speed of the front automobile; therefore, the driver in the rear automobile can take deceleration avoiding and braking emergency measures in advance to reduce rear-end collision accidents.
