[0002] With the development of technology in the past few decades, car lighting technology manufacturers have developed high-mounted brake lights not only to meet regulations, but their shapes have also become ever-changing with the design of car models. The miniaturization of external high-mounted brake lights has become more and more prominent. The design feature of through-type taillights is their continuous light strips, which makes the rear of the car look wider and more stable. At the same time, due to their unique visual effects, through-type taillights have higher recognition at night and in bad weather, thereby improving driving safety. In addition, the through-type taillight designs of different brands also have their own characteristics, showing the diversity and innovation of car design.

[0003] As one of them, the external through-type high-mounted brake light is usually located in the center or upper part of the rear of the car. The design has smooth lines, which can widen the horizontal visual effect and make the rear look more majestic. When the driver steps on the brake pedal, the brake light will be activated to remind surrounding vehicles and pedestrians of the vehicle's driving intention, including braking, thereby reducing the risk of rear-end collision.

[0004] In addition to the improvement of aesthetic design and safety, the development of external through-type high-mounted brake lights also benefits from consumers' increasing attention to vehicle safety functions and the government's increasingly stringent vehicle safety regulations.
