D1S HID Bulbs — OEM Replacement Pair for BMW, Audi & Cadillac

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 gradually, so a mismatched pair looks uneven on the road and provides sub-optimal lighting.

Our D1S pair is built in ISO:9006 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 into the original igniter — no ballast change required.

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.

Pair price, free Canadian shipping, free warranty, real Canadian phone support — only in 🍁. Our goal is to sell you an OEM-quality bulb at the best possible price. Our D1S bulbs are made from the same premium components and offer the same performance as Osram, Sylvania, and Philips OEM bulbs. We also have D1S Ballasts.

Our bulbs are available in all colours, with the original 4300K being the brightest, and lumen output decreasing as kelvin increases. We offer free shipping, free warranty, and free technical support. 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 only one thing, and doing it well. Buying the product on this page will get you a pair of bulbs, and we recommend replacing both as HIDs dim over time, but we can sell you a single bulb if you like, Contact us for a quote on a single or if we can be of any assistance.
