The lens is configured to form a light distribution associated with the reflection surfaces of the first reflector and the second reflector, respectively. The first light source, the first reflector, the second light source and the second reflector are arranged on the same mounting surface on the carrier; the application solves the problem of requiring high positioning accuracy and the need to reserve a given mounting dimension in the height direction due to the structural dimensions of the concave reflector itself when two concave reflectors are arranged in a stacked manner.

By setting the trapezoidal block, it is possible to block the light directly from the LED to the lens, and the blocking is dispersed and discontinuous. After the light emitted by the LED lamp is blocked by the trapezoidal block, the light pattern is adjusted so that the low-beam light distribution performance meets the requirements.
