15.2.3.3. Motorway beam

The motorway beam offers: l An improved visibility distance, up to 120 m, without glaring other vehicles. l A doubled intensity (120 lux) comparing to maximum possible intensity of the low beam. l An increased light-range by 60 meters.

“Motorway” class E modes – beam on the road

The class E mode of the passing beam (motorway light) has a higher luminous intensity and a raised cut-off offering increased forward visibility for the driver. To avoid glaring other road users it is only operated on roads where the traffic direction is separated by means of road construction, or, a sufficient lateral separation of opposing traffic is identified, a typical motorway condition. New technology based on sensors such as camera systems and GPS navigation can provide accurate information to determine if motorway conditions are fulfilled regardless of vehicle speed. l The “motorway” class E mode(s) of the passing beam shall not operate unless the vehicle’s speed exceeds 70 km/h and the road characteristics corresponding to motorway conditions are automatically detected.

In case of the following modes of class E, the cut-off aiming is adapted to the speed level.

The vehicle’s speed exceeds 100 km/h, the cut-off is set to 0.59% (0.34°) for a maximum Illumination range. The vehicle’s speed exceeds 90 km/h the cut-off is adjusted to 0.78% (0.45°) for a medium. Illumination range. The vehicle’s speed exceeds 80 km/h the cut-off is pulled down to 1% (0.57°) to avoid glare of opposing and oncoming vehicles.
