Fog lamps must be mounted at what height from the ground?

Fog lamps are specifically designed to illuminate the road immediately in front of a vehicle under low visibility conditions, such as fog, rain, or snow. The correct height for mounting fog lamps, which is in the range of 12 to 30 inches from the ground, is important because it helps to minimize the amount of light that is reflected back into the driver's eyes by the fog or precipitation. When fog lamps are positioned too low, they can become ineffective, whereas if they are placed too high, they risk creating glare and reducing visibility for both the driver and other road users.

This height range provides an optimal balance to enhance visibility just above the surface of the road while avoiding light being scattered back up into the atmosphere, which can often occur in dense fog conditions. Thus, mounting fog lamps within this specified range maximizes their utility and effectiveness during adverse weather situations.
