[0002] The brake light is a bulb in the taillight of a car. Its function is to emit a red light when the driver brakes to remind the vehicles behind to slow down or stop. It is usually installed on the rear of the car and the rearview mirror.

[0003] Existing automobile brake lights are usually composed of light distribution mirrors, inner mirrors, optical parts, mounting brackets, lamp housings, and other structural plastic parts. The large number of structural parts makes the cost high, and the brake light uses a dot matrix LED lamp for lighting, that is, an LED is arranged every 12 mm or so, resulting in a large number of LEDs and high costs. In addition, multiple light guide brackets are required to install and fix the light guide. There is a mounting structure in the middle area of ​​the light guide. After lighting, the mounting structure partially reflects light, resulting in a bright spot after lighting; in addition, for a light guide type high-mounted brake light, it can be seen from the appearance before lighting that the mounting structure of the internal light guide affects the appearance. Therefore, in view of this, the inventor provides a small-sized and streamlined brake light for an automobile to solve the above problems. Utility Model Content
