Specifically, the lamp shade is internally provided with an installation space, the first light source and the second light source are both in electric signal connection on the circuit board, and the first light source and the second light source are both LED lamps. The purpose of this design is, can realize position lamp function and indicator light function simultaneously in compact structure, satisfied the demand of car light to multiple signal function. Optionally, the circuit board is mounted inside the lamp shade and fixed on the lamp shade, the internal space of the lamp shade can be divided into a first cavity (a first reflection cavity) and a second cavity (a second reflection cavity) by the circuit board, and light emitted by the first light source is reflected to the outside of the lamp shade from a first light-emitting surface of the first reflection cavity by the first reflection structure, so as to realize the position lamp function; the light emitted by the second light source is reflected to the outside of the lampshade from the second light-emitting surface of the second reflection cavity through the second reflection structure, so that the steering lamp function is realized. The circuit board is a double-sided circuit board prepared from FR-4 grade materials. The first light source and the second light source are respectively connected with the upper surface and the lower surface of the circuit board through electric signals, and the first light source (LED lamp) and the second light source

The LED lamps are respectively arranged on the two sides of the circuit board in a vertically staggered manner, so that heat dissipation is facilitated, and the service life is prolonged. Two LED lamps are arranged on the upper surface and the lower surface of the circuit board and are respectively used for illuminating the first reflection cavity and the second reflection cavity, so that the functions of a position lamp and a steering lamp are respectively realized. Specifically, after the first light source (LED lamp) illuminates the first reflective cavity, light emitted by the first light source (LED lamp) is reflected by the first reflective structure, so that the light is emitted from the first light emitting surface of the first cavity to the outside of the lamp cover, that is, the position lamp function is realized; after the second light source (LED lamp) illuminates the second reflection cavity, light emitted by the second light source is reflected by the reflection structure, so that the light is emitted to the outside of the lampshade from the second light emitting surface of the second cavity, namely, the function of the turn light is realized, and the function of the position light and the function of the turn light are simultaneously realized in a compact structure.
