A heat sink and a fan are located at the rear of the lamp core to accelerate heat dissipation. A small fan is located at the top of the lamp core; after the lamp core and lamp housing are assembled, this small fan is inside the lamp housing. The rotation of the small fan quickly blows the heat from the lamp core into the interior of the lamp housing and to the bottom of the transparent cover, rapidly raising the temperature of the air inside the lamp housing assembly and the transparent cover. In frosty or snowy weather, this quickly melts the frost and snow on the outer surface of the transparent cover, allowing the main light to shine out normally for driving illumination.

The main light source lamp core is designed as a triangular three-dimensional shape, with an LED on each of the three sides. The three LEDs are fixed at the focal points of the three bowl-shaped reflectors inside the lamp cover assembly. The light emitted by the LEDs is reflected by the bowl-shaped reflectors, forming two driving light patterns for high and low beams. When disassembling the light source module, loosen the lamp core fixing screw 4 to release the positioning constraint between the lamp core assembly 2 and the lamp cover rear shell 11, pull out the lamp core module along the axial direction of the positioning post, and disconnect the electrical connection. When disassembling the optical reflector module, loosen the rear cover fixing screw 7 to release the fixation between the lamp cover assembly 1 and the front cover 5 and the mounting bracket 8, lift the lamp cover rear shell 11 upwards, and separate the electrical interface of the daytime running light source board 14.
