What does the Audi A4L look like with the fog lights on?

Audi A4L's fog lights become bright when turned on. Introduction to fog lights: When driving in adverse weather conditions such as fog, snow, and heavy rain, or in smoke-filled environments, front fog lights are essential to illuminate the road ahead and ensure driving safety. In recent years, in terms of styling design, fog lights are often installed on the front bumper. Principle of fog lights: The light source filament is designed at the focal point of the reflector's parabola. After being reflected by the reflector, it forms a beam parallel to the optical axis. The diffuser lens spreads and refracts the beam to form a wider horizontal beam, ensuring that the light pattern and illumination meet regulatory requirements.
As an Audi A4L owner, I can share how the fog lights look when turned on during daily driving. Every time I activate them in foggy conditions, two soft white light beams illuminate below the front bumper, positioned about 30 centimeters above the ground. The beams don't project straight forward but spread out horizontally like a fan, covering approximately ten meters of the road ahead. The color is a bright incandescent white, resembling clean moonlight, which makes roadside vegetation, stones, and lane markings appear particularly clear when penetrating thick fog. I often think this design is really thoughtful—the LED light source is energy-efficient and durable, providing sufficient brightness without being glaring. Turning them on only when necessary enhances safety. However, avoid using them unnecessarily on clear days to prevent dazzling oncoming drivers. Regularly cleaning the lamp covers to maintain light transmission ensures optimal fog light performance.
