Description

technical field

[0001] The invention relates to an early warning device when a vehicle brakes, in particular to an improvement of a brake early warning device, which belongs to the technical field of vehicle accessories. Background technique

[0002] As we all know, when the vehicle is braking, the brake lights at the rear of the vehicle are always on, which can serve as a warning to subsequent vehicles to slow down and prevent rear-end collisions. With the rapid extension of the expressway and the continuous increase of vehicle speed, the shortcomings of this early warning method have become obvious, that is, the driver of the vehicle behind cannot perceive the speed of braking of the vehicle in front and the length of the braking time according to the status of the brake lights.

[0003] For this reason, the Chinese invention patent that the application number is 93108373.7, and the application date is 1993.07.16 discloses a kind of brake light warning device with multi-st...
