==== History ====
In 1992 the first production low beam HID headlamps were manufactured by [[Hella (company)|Hella]] and [[Robert Bosch GmbH|Bosch]] beginning in 1992 for optional availability on the [[BMW 7 Series (E32)|BMW 7 Series]].<ref name="100Hella">{{cite book |last1=Behrend |first1=Jürgen |title=Hella 1899-1999 |page=97}}</ref><ref name="Litronic">{{cite journal |title=Litronic – New Automotive Headlamp Technology with Gas Discharge lamp |journal=Automotive Design Engineering |year=1993 |last1=Neumann |first1=Rainer |last2=Woerner |first2=B. |pages=152–156}}</ref> This first system uses a built-in, non-replaceable bulb without a UV-blocking glass shield or touch-sensitive electrical safety cutout, designated D1<ref>{{cite report |chapter=Improved Projector Headlamps Using HID (Litronic) and Incandescent Bulbs |publisher=SAE International |year=1994 |last=Neumann |first=Rainer |title=SAE Technical Paper Series |volume=1 |chapter-url=http://papers.sae.org/940636/ |access-date=2014-12-13 |doi=10.4271/940636}}</ref> – a designation that would be recycled years later for a wholly different type of lamp. The AC ballast is about the size of a building brick.
In 1996 the first American-made effort at HID headlamps was on the 1996–98 [[Lincoln Mark VIII]], which uses reflector headlamps with an unmasked, integral-ignitor lamp made by [[Osram Sylvania|Sylvania]] and designated ''Type 9500''. This was the only system to operate on [[Direct current|DC]], since reliability proved inferior to the AC systems.{{citation needed|date=November 2012}} The Type 9500 system was not used on any other models, and was discontinued after [[Osram]]'s takeover of Sylvania in 1997.{{Citation needed|date=April 2012}} All HID headlamps worldwide presently use the standardized AC-operated bulbs and ballasts.
In 1999 the first worldwide HID headlights for both low and high beam were introduced on the [[Mercedes-Benz CL-Class (C215)]].<ref>http://media.daimler.com/dcmedia/0-921-614233-1-820664-1-0-0-0-0-1-11702-854934-0-1-0-0-0-0-0.html {{Webarchive|url=https://archive.today/20141230100212/http://media.daimler.com/dcmedia/0-921-614233-1-820664-1-0-0-0-0-1-11702-854934-0-1-0-0-0-0-0.html |date=30 December 2014 }} The history of the headlamp: From the candle lamp to motorway mode</ref><ref>{{Cite web|url=https://www.carsome.my/news/item/piercing-the-dark-mercedes-benzs-vehicle-lightings-have-come-a-long-way-part-1-of-2|title=Piercing the dark: Mercedes-Benz's vehicle lightings have come a long way – Part 1 of 2|access-date=28 November 2023|website=carsome.my|date=23 January 2020 }}</ref>
