[0002] Automobiles are usually equipped with signal lights at specific locations such as the head, which are turned on during daytime driving or turning to alert pedestrians or vehicles around the motor vehicle and ensure safe driving of the motor vehicle.
[0003] However, most of the existing signal lights have a single function and can only be used as daytime running lights or turn signals. At present, to realize the daytime running and turn reminder functions, two sets of light guide structures with different functions need to be installed inside the lamp housing.

[0035] It can be understood that the method of using the multiplexed vehicle light module is as follows: the multiplexed vehicle light module can be used as a turn signal, a daytime running light, a position light and a marker light. When it is used as a daytime running light or a position light, in the universal light guide structure 10, the LED fill light unit 42 keeps the second long light conductor 14 on and the LED two-color light unit 41 keeps the first long light conductor 13 on. The second long light conductor 14 fills the first long light conductor 13 with light, so that the lighting effect is more uniform, and the LED two-color light unit 41 keeps the first long light conductor 13 on. The light color of the light emitted by the light sheet unit 41 when the first long optical conductor 13 is lit is white; in the universal auxiliary lamp structure 20, the LED upper light sheet group and the LED lower light sheet group emit the same white light as the LED two-color light sheet unit 41, which is reflected by the upper reflection bowl 2111 and the lower reflection bowl 2121 and guided to the upper light emitting grid 1141 and the lower light emitting grid 1151; thereby, the white light emitted by the universal optical waveguide structure 10 and the universal auxiliary lamp structure 20 illuminates the inner lens segment 511 and penetrates the inner lens segment 511 to be exported to the outside.
[0036] When it is used as a turn signal, the LED fill light sheet unit 42 keeps the second long optical conductor 14 on and the LED two-color light sheet unit 41 intermittently lights the first long optical conductor 13, and the LED two-color light sheet unit 41 lights up the first long optical conductor 13 in yellow; in the universal auxiliary lamp structure 20, the LED upper light sheet group and the LED lower light sheet group intermittently light up the same yellow light as the LED two-color light sheet unit 41, and are reflected by the upper reflection bowl 2111 and the lower reflection bowl 2121 to guide the upper light emitting grid 1141 and the lower light emitting grid 1151; thereby, the yellow light emitted by the universal optical waveguide structure 10 and the universal auxiliary lamp structure 20 intermittently lights up the inner lens segment 511 and penetrates the inner lens segment 511 to be output to the outside.
[0037] When used as a marking light, the LED logo light sheet 401 lights up the light-emitting surface 321 with the logo of the short light guide strip 32 , so that the logo exposed from the light outlet 521 is clear and obvious.

[0040] Further, see Figure 7In this embodiment, the heat sink 12 is provided with a plurality of heat sinks 121 at its rear end and a heat sink arm 122 extending toward the middle of the auxiliary lamp bracket 21 on its inner side, so that the heat sink arm 122 abuts against the back of the aisle 2131 of the auxiliary lamp bracket 21 to assist in heat dissipation.
[0041] Furthermore, in this embodiment, the heat sink 12 is provided with assembly holes 123 at its rear end, outer edge and inner edge for connecting with the inner wall of the shell cavity 102 .
[0042] Furthermore, in this embodiment, the auxiliary light shield 52 is provided with decorative sheets 522 on the upper and lower parts of the outer surface thereof, and the light outlet 521 is located between the two decorative sheets 522 .
[0043] Further, see Fig.12 In this embodiment, the auxiliary light shield 52 is provided with an upper buckle piece 523 at its top for buckling with the bottom edge of the upper connecting portion 1142 and a lower buckle piece 524 at its bottom for buckling with the top edge of the lower connecting portion 1152.
