1. A safety system for alerting a speed of a vehicle, comprising:

  • a rotary unit;

    an elastic element having one end engaged to the rotary unit;

    a base, a side of the base having a via hole;

    the base having a groove;

    the rotary unit being placed upon the groove of the base;

    a control circuit board seat connected to a brake bulb and a power plug;

    a switch of the control circuit board seat being inserted into the base and the rotary unit;

    a plurality of studs serving to lock the control circuit board seat to the base;

    the rotary unit being wound with a connecting wire which passes through the via hole;

    an outer cover being fixed upon an upper side of the groove of the base by using screws so as to seal the groove;

    wherein the connecting wire winds around the rotary unit and is connected to the actuated switch and then is connected to a throttle pedal or an acceleration rope in the engine chamber;

    the control circuit board seat is connected to a power source;

    when the connecting wire is pulled and then returned, the rotary unit will control the actuation switch, and the elastic element will generate a resilient force due to rotation so that the connecting wire will return automatically to drive the switch of the control circuit board seat to generate control signals;

    the control circuit board seat controls the brake bulb to flash;

    a driver at a front car will release the throttle pedal to make a control box to cause the rear light to flash;

    thus the driver of the rear car has a longer reaction time for braking.
