The design idea of the fool warning light is to prevent the rear end traffic accident from happening. It enables the rear car to distinguish the front car from the front car in terms of quick braking or slow braking. With it, in case of emergency braking, sudden deceleration or collision, the warning light will automatically light up and flicker in an instant. By using the alert of the driver of the rear car to the warning light of the front car, the measures of deceleration and avoidance shall be taken in advance to effectively avoid or reduce the occurrence of rear end accidents.

Since the fool warning light is so useful, why can't it get people's attention? I personally think there are two reasons. One is that my lack of funds and personal weakness lead to insufficient market guidance. Second, people think "is it worth it?" This idea is worth discussing. Because, buy a car from tens of thousands to tens of millions, a set of fool warning lights to buy 398 yuan, how much is a life worth? How much is a family's life worth? "It's not worth it", not to mention the accident. Even if there is no fool's warning light and the car is hit by the rear end in case of emergency braking, do you want money for repairing the car? Do you want time? Is time valuable? Are people upset? I went out for a self driving tour with my girlfriend, but my interest was broken because I was going to repair the car. Is it worth it?

What's the use of a fool's warning light? A fool's warning light is just like a fool's camera. A person with poor photography skills can take good pictures with a fool's camera. If the driver's skill is not good, as long as you install a fool warning light on his car, he will not have a rear end accident. For example, many things are achieved subjectively by means of science and technology. Not to say, my technology is good, don't fool the warning light will not be rear ended, since everyone's technology is so good, then why do many car rear end accidents happen frequently and die heavily in the fog period? In fact, when most people encounter rainy, foggy and dusty weather, as long as there is a fool's warning light on the car, they can drive safely.

There is no doubt that a car with a fool's warning light is much safer than a car without a fool's warning light. Of course, under the premise of similar driver technology. In other words, when the same person drives a car with or without a fool's warning light, the probability of accident is less. As for the small probability, whether it's much smaller or a little smaller, whether it's worth spending more money is a matter of opinion. Anyway, I personally think that life is priceless. If I can afford a car, I can afford a fool's warning light, because it's completely possible for him to nip the rear end accident in the bud and ensure the safety of my family's life and property.
