Which light is classified as a convenience light?

Fog lights are classified as convenience lights because they are designed to enhance visibility under specific driving conditions, particularly during fog, rain, or snowfall. Unlike standard headlights, which illuminate the road ahead in general driving situations, fog lights are mounted lower to the ground and project a wide, low beam of light that helps reduce the amount of light that is reflected back at the driver by fog, rain, or snow. This makes them particularly useful for improving visibility in adverse weather conditions, thereby offering a level of convenience for the driver.

In contrast, brake lights, headlights, and turn signals serve more critical functions related to safety and communication on the road. Brake lights signal when a vehicle is slowing down or stopping, headlights provide general illumination for nighttime driving, and turn signals indicate a driver's intention to change direction. Each of these lights is essential for safe driving but does not fit the specific definition of convenience lights as closely as fog lights do.
