Why Does Only One Reversing Light Illuminate?
2 Answers
For Volkswagen vehicles, only one reversing light illuminates because a single light makes it easier for drivers to identify. Below are the reasons why only one reversing light is on and an introduction to the installation position of reversing lights: Reasons for Only One Reversing Light Illuminating: Since 2001, China's traffic laws have been revised to require that each vehicle be equipped with at least one fog light and one reversing light. Vehicles shorter than 6 meters are mandated to have one reversing light, with the other being optional. In practice, a single reversing light is more noticeable to drivers, as symmetrical lighting might cause a numbing effect, potentially leading drivers to mistake the vehicle ahead for one driving in the wrong direction. A single light is easier to recognize. Installation Position of Reversing Lights: The position of reversing lights is also regulated by the state. Reversing lights are generally installed on the right side of the vehicle's rear. Since China follows left-hand drive, placing the reversing light on the right helps drivers reverse and park on the right side of the road at night, complying with national regulations while reducing production costs.
I've noticed that it's quite common for only one reverse light to be on, especially in older cars. This design is actually for safety considerations. Reverse lights are very bright—if both were on during nighttime reversing, it could dazzle or distract drivers behind. If mistaken for brake lights, it might even cause a rear-end collision. I've observed many cars, and cost-saving by manufacturers is another reason—installing just one light reduces manufacturing costs and simplifies wiring. Additionally, some countries' regulations permit single reverse light designs. For example, under certain EU standards, it serves as auxiliary lighting and doesn’t need to be symmetrical like taillights. Having worked on cars myself, I know bulb or wiring issues could cause the other light not to work, but if it’s the original design, there’s no problem. So don’t worry—just pay attention to your mirrors while driving. Though simple, this design helps keep everyone safe.
