The invention provides a rear-end collision preventing alarm lamp. An ultrasonic emitter is arranged at the position, close to automobile reversing radar, on a rear bumper bar of an automobile. A signal line of the automobile reversing radar is connected to the input end of a processing chip. The output end of the processing chip is further connected with an alarm taillight, and the alarm taillight is arranged in an automobile back light box. A hardness structure of the rear-end collision preventing alarm lamp can be combined with the automobile to solve the problem that in the prior art, a rear-end collision preventing product capable of being applied to the automobile and giving out an alarm when the distance of two automobiles is smaller than the safe distance is lacked. The invention further provides a rear-end collision preventing alarm lamp processing method. Comprehensive judgment can be conducted according to current automobile speed and the speed difference and the distance difference of the previous automobile and the next automobile, the alarm taillight is controlled to flicker at different frequencies, and the more dangerous the condition is, the flickering frequency of the alarm taillight is higher. In this way, the dangerous degree of the distance between the next automobile and the previous automobile can be known visually and more conveniently for a driver of the next automobile, the travel speed can be controlled accordingly, and the possibility of the rear-end collision of the automobiles is lowered.
