D1S HID Bulbs (Pair) — OEM Xenon Headlight Replacement Bulb

D1S HID xenon bulbs are the OEM replacement pair for many factory HID vehicles in Canada. BMW, Mercedes-Benz, and Audi all used D1S in many factory applications, and this pair replaces all D1S including Philips 85410, Osram 66140, and Osram 66144 bulbs for direct plug-and-play installation.

D1S bulbs are the factory HID part fitted to dozens of European and North American vehicles from roughly 2003 onward — BMW 5- and 7-Series (E60/E65), Audi A4/A6/Q7, Cadillac SRX and CTS, Land Rover Range Rover, Mini Cooper and others. When one dims, both should be replaced — HID output drops and bulbs colour shift over time, so a mismatched pair looks uneven on the road and provides sub-optimal lighting.

Our D1S pair is built in ISO:9001 facilities on the same Osram OEM architecture as the bulb that came out of your headlight. UV-cut quartz glass, metal centring posts, E4/E11/ECE rated, DOT-approved in the 4300K option. They install plug-and-play with the original ballast.

If you're not sure which bulb your car uses, check our factory HID bulb guide or call us and we'll confirm in two minutes.

Free Canadian shipping, free warranty, and real Canadian phone support are included. Our goal is to sell you an OEM-quality bulb at the best possible price. Our D1S bulbs are built from the same premium components and offer the same performance as Osram, Sylvania, and Philips OEM bulbs. Our bulbs are available in multiple color temperatures, with 4300K being the brightest OEM-style option and output decreasing as kelvin increases.  We were Canada's first online HID retailer, and have been providing Canadians with the highest quality automotive lighting since 2008. We sell only lighting, and only in Canada, because we believe in doing one thing well. Buying this product gets you a pair of bulbs, and we recommend replacing both because HIDs dim over time. We can also sell you a single bulb if needed — contact us for a quote. We also have D1S Ballasts.
