This utility model belongs to the technical field of reversing light drive circuits, specifically an integrated drive circuit for a rear fog reversing light, including a rear fog light control module, a reversing light control module, and an LED chip module. The rear fog light control module is connected to both the reversing light control module and the LED chip module. The LED chip module is also connected to both the rear fog light control module and the reversing light control module. In this application, the LED driver ensures that the LED current remains constant when the input voltage changes from 9V to 16V, allowing the LED brightness to vary within a small range, thus ensuring consistent product brightness. It simplifies the assembly process, reduces manual soldering and wiring harness installation time, and improves production line efficiency. Compared to discrete component circuits, the LED driver chip-level integrated solution has stronger vibration and electromagnetic interference resistance, reducing the probability of failure.
