6478 Lufft's VS2k-UMB visibility sensor for road weather stations and traffic control systems, which replaces the VS20-UMB, measures visibility up to 2,000 metres and features an optimised housing alloy that is water resistant even under extreme conditions.

The device also features an optional calibration kit, forward light scattering technique, sea waterproof housing and active spider defence.
