How many rear fog lights does the Passat have?

The Passat has only one rear fog light and one reverse light. The function of automotive fog lights: Automotive fog lights are used to illuminate the road and provide safety warnings during rainy or foggy weather conditions, improving visibility for both the driver and surrounding traffic participants. Fog lights generally refer to automotive fog lights, which are installed on the front and rear of the vehicle. Classification of automotive fog lights: Based on installation position, automotive fog lights can be divided into front fog lights and rear fog lights. Based on the principle of light emission, they can be categorized into gas automotive fog lights and LED automotive fog lights. Audi has recently developed a laser fog light.
From a vehicle design perspective, the Passat typically has only one rear fog light, located on the left side of the rear. This is primarily due to international automotive safety regulations to prevent confusion between rear fog lights and brake lights, hence the single light design for clear warning to other drivers. Having driven a Passat for several years, I've noticed that only the left light illuminates when activating the rear fog lights in rainy or foggy conditions, which effectively avoids misunderstandings in low visibility. If you inspect the rear of your vehicle, you'll find most Passat models lack a fog light on the right side, while the left one is standard equipment. This design proves particularly useful on slippery roads, but remember to use fog lights only in fog or snow conditions and turn them off otherwise to prevent excessive battery drain. I recommend checking its brightness and connection during annual maintenance.
As a seasoned long-distance driver, I've encountered the issue with the Passat's rear fog light several times. Generally, it only has one rear fog light, fixed on the left side of the rear. Turning it on is straightforward—just locate the fog light switch near the steering wheel and press it, which will only illuminate the left light. This design is quite reasonable because having multiple fog lights could confuse other drivers into mistaking them for brake lights, increasing the risk of rear-end collisions. From my observations at repair shops and discussions with fellow car enthusiasts, we all agree that while rear fog lights are used infrequently, they are crucial and must be reliable. I recommend that new car owners test the light periodically to ensure it's functioning properly, especially before the rainy season. If any damage or wiring issues are found, get them fixed promptly.
