What is the minimum height for fog lights from the ground?

Fog lights are designed to illuminate the road immediately in front of the vehicle when visibility is poor due to weather conditions such as fog, rain, or snow. The proper positioning of these lights is essential to ensure that they provide the most effective illumination without causing glare for other drivers.

The minimum height requirement for fog lights from the ground is set to ensure that the light beam is low enough to be effective in scattering through fog or rain, which tends to be closer to the ground. By placing fog lights at a minimum height of 12 inches, it allows for optimal performance in these conditions. This height helps to avoid the bright reflection off moisture in the air, which can result when lights are too high, causing reduced visibility instead of improved clarity.

Higher or improperly positioned fog lights may not only hinder their functionality but could also contravene safety regulations that aim to ensure that all vehicle lighting systems are compliant and do not impede the visibility of other road users.
