<p>PROBLEM TO BE SOLVED: To call, the following vehicle's attention and press it to reduce the speed so as to enhance the safety of traveling by bringing only the circular arc parts of a first spring piece pair or both the circular arc parts of the first spring piece pair and a second spring piece pair into contact to each other to light or flash a stop lamp. SOLUTION: When a vehicle is stopped for a short time by a red light, a stop lamp is lighted to call the following vehicle's attention by separating the first spring piece and second spring piece of a second spring piece pair 22. In a sudden braking, the downward operating distance of a brake pedal 40 is increased, and the distance of a rod 111 relatively moving outward beyond a stop lamp switch 20 is also increased. If the moving distance of the rod 111 exceeds the second spring piece pair 22, the second spring piece pair 22 is closed by elastic force, and a flasher 30 controls the stop lamp, so that it is quickly ON/OFF operated to produce a quick flash instruction effect. Thus, the following vehicle is urged to take a quick reaction, so that the collision can be prevented.</p> |
