The three-layered display includes 84 individual controllable LEDs per headlamp that vary light distribution depending on traffic, weather and road conditions. The integrated adaptive High Beam Assistant Plus allows more frequent use of the vehicle’s high beams, offering greater safety and comfort. Unlike static high-beam headlamps, Daimler’s adaptive high-beam function can selectively mask light patterns directed at oncoming vehicles within a fraction of a second. The system uses a windshield-mounted camera to assess the driving environment. The adaptive system blocks light aimed directly at an oncoming vehicle, but still illuminates the areas adjacent to oncoming traffic. It provides maximum illumination of the roadway for the driver and prevents glare for oncoming drivers.

A newly developed adverse weather light also reduces glare from the roadway when it is raining by specifically dimming individual LEDs in the low beam. The system reduces glare from illuminated road signs by selectively reducing the brightness of individual LEDs. Two light guides above the main headlamp generate the direction indicators, daytime running lights and position lights. Transparent silicone plastics are used as the primary optics for an LED headlamp, directing the light from the 84 individual LEDs to the front lens itself tucked behind a focusing outer lens of the LED headlamp module.
