Which light is classified as a convenience light?

A fog light is classified as a convenience light because its primary function is to enhance visibility in specific driving conditions, particularly during foggy weather. Fog lights are designed to emit a low, wide beam of light that illuminates the road immediately in front of the vehicle, reducing the amount of light that is reflected back by fog, rain, or snow. This makes it easier for drivers to see the road and any potential hazards when visibility is compromised.

In contrast, brake lights are safety lights that indicate when a driver is slowing down or stopping, headlight functions are essential for general illumination during night or low-light conditions, and turn signals serve to communicate a driver's intentions to other road users for safe lane changes and turns. These functions are crucial for road safety and compliance rather than convenience, which differentiates them from fog lights as convenience lights.
