[0023] A type of motor vehicle turn signal module, such as Figure 1-4As shown, it includes a housing 1, a connecting component, a projection light module, and a turn signal module. The connecting component is connected to the housing 1 for connection with a motor vehicle. A turn signal window is provided on the front of the housing 1, and a projection window 10 is provided on the bottom of the housing 1. The projection light module and the turn signal module are both installed inside the housing 1, wherein the turn signal module faces the turn signal window, and the projection light module is arranged at an angle inside the housing 1 and faces the turn signal window. Specifically, by integrating turn signals and projection lights, a multi-functional integrated design is achieved. At the same time, by tilting the projection light module, its light axis is projected onto the ground at a specific angle, enabling ground projection warnings (such as arrows and text) to enhance safety at night or in low-visibility environments.

[0024] Preferably, the housing 1 includes a rear housing 102 and a light-transmitting cover 101 that are detachably connected to each other.
