The control unit includes a rechargeable lithium battery BT, a microcontroller control unit, an LED display group, and a charging management circuit. The charging management circuit is electrically connected to the microcontroller control unit and the rechargeable lithium battery BT. The microcontroller control unit includes a microcontroller U1. The LED display group includes eight parallel-connected display units 10-2, which are arranged in a ring on the lamp housing 10-1. Two sets of display units 10-2 are provided on each side of the lamp housing 10-1. Each set of display units 10-2 includes a voltage divider resistor 10-2-1 and a light-emitting diode 10-2-1 connected in series between the I / O port of the microcontroller U1 and the ground terminal GND. In this embodiment, the microcontroller is a general microcontroller, and the specific model is conventional technology in this field, so it will not be described in detail. In this embodiment, the display units 10-2 are arranged in a ring on the taillight body 10, which makes the lighting range wider and the lighting brightness brighter.
[0022] Preferably, the microcontroller control unit further includes a third resistor R3, a first capacitor C1, and a push-button switch 11. The push-button switch 11 is fixed to the upper surface of the lamp housing 10-1.

[0025] With the above structural setup, during operation, the triangular clamp 1-1 is first secured to the bicycle taillight frame. Then, by pressing down the operating wrench 7, the swing arm 3 rotates downward. At this time, the hook clamp 6, under the action of the side arc surface 5, ensures that the lower opening of the hook clamp 6 is raised, widening the opening of clamp 1-2. When the operating wrench 7 is raised upward, the swing arm 3 rotates upward. At this time, the hook clamp 6, under the action of the side arc surface 5, ensures that the lower opening of the hook clamp 6 is pressed downward, ultimately pressing the bicycle rear frame tightly into clamp 1-2. Furthermore, since the inside of clamp 1-2 is a silicone anti-slip layer 1-1-2, it not only provides anti-slip properties but also further presses the bicycle firmly. The frame, through the cooperation of the side metal part 602 and the magnet part 1-1-1 (using a strong magnetic material), ensures that once the magnet part 1-1-1 and the metal part 602 are magnetically attracted, they are not easy to loosen. Only external force can ensure that the metal part 602 and the magnet part 1-1-1 are separated, which further avoids the problem of loosening due to bicycle vibration and further improves the clamping effect. Therefore, this structure can be disassembled, making it convenient for users to install it in any position on the bicycle. In addition, since the taillight body 10 and the taillight base 1 are hinged in this structure, the lighting adjustment of the taillight body 10 can be adjusted, which can better meet the needs of users.

Preferably, to improve the fixing effect, a hook 8-1 is provided on the side of the taillight holder 1, and an elastic lug 9-1 that cooperates with the hook 8-1 is provided on the outer side of the hook 601. The elastic lug 9-1 is provided with a through hole. When the through hole is fitted onto the hook 8-1 later, the clamp 1-2 can be further locked and positioned, avoiding the problem of the device being easily loosened due to the vibration of the bicycle when it is installed on the rear frame of the bicycle.
