Why does Volkswagen have only one reversing light on?

Volkswagen has only one reversing light on because the other side is a rear fog light. Function of car reversing lights: Reversing lights are installed at the rear of the car to illuminate the road behind when reversing and serve as a warning to vehicles and pedestrians behind, indicating that the car is reversing. All reversing lights are white. Generally, they only turn on when reversing. Regulations on reversing light settings: For vehicles with a length of less than 6 meters, one reversing light is mandatory, and an additional one can be optionally installed. If there is only one reversing light, it must be located on the left side. Reducing one reversing light and one fog light also benefits the owner, as symmetrical lighting can cause a numbing reaction in drivers, while a single light can better attract the driver's attention.

I've been driving a Volkswagen for several years and noticed that only one side of the reverse light comes on. At first, I thought it was broken, but later a mechanic friend told me this is completely normal. He explained that it's designed this way because regulations only require one reverse light, and there's no need for two. The main purpose is to alert vehicles behind that you're reversing, not for illumination. Many other cars, like Hondas and BMWs, also have only one light on. The reason might be to simplify the system, reduce potential failure points, and save on manufacturing costs. If you notice the other side isn't lit, don't worry—it's not a problem. But if both lights go out when reversing, you should check the fuse or wiring. In daily driving, as long as the light is on, it effectively alerts others. Safety first, after all.

As a car enthusiast, I've studied the design of Volkswagen's reverse lights. The fact that usually only one light illuminates is because it's essentially a signal light. Automakers opt for a single bulb instead of two to control complexity and costs, meeting regulatory requirements while avoiding redundancy. This reduces wiring layout difficulties and potential short-circuit risks. Additionally, reverse lights aren't primary illumination sources; they just need to provide a warning signal. Excessive brightness could actually impair visibility. From my experience, regularly checking bulb condition is crucial, and when replacing, prioritizing OEM parts ensures compatibility. In summary, this design is common in European and American cars, aiming for practicality without wasting resources.

From my driving experience, Volkswagen's single-sided reverse light is quite reasonable. It only activates when reversing, serving as a warning signal where one light is sufficient to clearly convey the message. Regulations mandate reverse lights but permit a single-light configuration to avoid confusion with other lights, such as preventing it from being mistaken for a brake light. This design also considers energy efficiency and low maintenance requirements. I once encountered a situation where the right light was on while the left wasn't, but it functioned normally as long as the bulb was replaced promptly.
