A ''glare-free high beam'' is a camera-driven dynamic lighting control strategy that selectively shades spots and slices out of the high beam pattern to protect other road users from glare, while continuously providing the driver with maximum seeing range.<ref>{{cite web|url=https://paginas.fe.up.pt/~ee04007/tese/docs/AutoIndustrie_gb_ti_lt.pdf|title=Lighting technology|access-date=17 February 2010}}</ref> The area surrounding other road users is constantly illuminated at high beam intensity, but without the glare that would typically result from using uncontrolled high beams in traffic.<ref>{{cite web|url=https://www.youtube.com/watch?v=C6mmQxfqo7o| archive-url=https://ghostarchive.org/varchive/youtube/20211117/C6mmQxfqo7o| archive-date=2021-11-17 | url-status=live|title=Mobileye & Visteon| website=[[YouTube]]| date=9 December 2009|access-date=18 February 2010}}{{cbignore}}</ref> This constantly changing beam pattern requires complex sensors, microprocessors, and actuators because the vehicles which must be shadowed out of the beam are constantly moving. The dynamic shadowing can be achieved with movable shadow masks shifted within the light path inside the headlamp. Or, the effect can be achieved by selectively darkening addressable LED emitters or reflector/mirror elements, a technique known as ''pixel light''.<ref>{{cite web|url=http://www.drivingvisionnews.com/reports/technical-survey-and-regulations/2492-adaptative-lighting-systems |title=Adaptive Lighting Systems |publisher=Driving Vision News |date=2010-08-31 |access-date=2012-01-31}}</ref>

The first mechanically controlled (non-LED), glare-free high beam was Volkswagen's "Dynamic Light Assist" package,<ref>{{cite press release|url=https://www.volkswagen-media-services.com/medias_publish/ms/content/en/pressemitteilungen/2010/02/10/to_the_point__world.standard.gid-oeffentlichkeit.html |title=New Touareg takes the SUV idea into the future|access-date=17 February 2010|archive-url= https://web.archive.org/web/20120303155255/https://www.volkswagen-media-services.com/medias_publish/ms/content/en/pressemitteilungen/2010/02/10/to_the_point__world.standard.gid-oeffentlichkeit.html |archive-date=3 March 2012|url-status=dead}}</ref> which was introduced in 2010 on the [[Volkswagen Touareg]],<ref>{{cite press release|url= http://media.vw.com/index.php?s=43&item=582|title=The New Volkswagen Touareg SUV is One of the Safest Automobiles of All Time|access-date=17 March 2010|archive-url= https://web.archive.org/web/20120313052937/http://media.vw.com/index.php?s=43&item=582|archive-date=13 March 2012|url-status=dead}}</ref> [[Volkswagen Phaeton|Phaeton]],<ref>{{cite press release|url= https://www.volkswagen-media-services.com/medias_publish/ms/content/en/pressemitteilungen/2010/04/22/phaeton_debuts_with.standard.gid-oeffentlichkeit.html |title=Phaeton debuts with new design and new technologies|access-date=22 April 2010|archive-url=https://web.archive.org/web/20110720152841/https://www.volkswagen-media-services.com/medias_publish/ms/content/en/pressemitteilungen/2010/04/22/phaeton_debuts_with.standard.gid-oeffentlichkeit.html|archive-date=20 July 2011|url-status=dead}}</ref> and [[Volkswagen Passat|Passat]]. In 2012, the facelifted [[Lexus LS (XF40)]] introduced an identical bi-xenon system: "Adaptive High-beam System".

The first mechanically controlled LED glare-free headlamps were introduced in 2012 on [[BMW 7 Series (F01)#2012 update|BMW 7 Series]]: "Selective Beam" (anti-dazzle high-beam assistant). In 2013 [[Mercedes-Benz]] introduced the same LED system: "Adaptive Highbeam Assist Plus".

The first digitally controlled LED glare-free headlamps were introduced in 2013 on Audi A8. See [[#LED|LED section]].
