Why does the Civic's rear fog light only illuminate on one side?

The reason why the Civic's rear fog light only illuminates on one side is that the vehicle is designed with a single rear fog light, while the opposite side functions as a reverse light. The purpose of fog lights is to illuminate the road during rainy or foggy weather conditions, enhancing visibility for both the driver and other road users, allowing approaching vehicles and pedestrians to detect each other from a greater distance. Taking the Honda Civic 2021 HATCHBACK 220TURBO CVT as an example, it is a compact car launched by Dongfeng Honda with dimensions of 4517mm in length, 1799mm in width, and 1434mm in height, featuring a wheelbase of 2700mm. It is equipped with a 1.5T turbocharged engine delivering a maximum power of 130kW and a peak torque of 220Nm, paired with a CVT continuously variable transmission.
