Collection: D1S HID Bulbs, Ballasts & Kits

This collection includes OEM-style D1S HID bulbs, universal ballasts and complete D1S headlight kits for vehicles equipped with factory-installed D1S xenon headlights.
D1S bulbs use a built-in igniter and were fitted to many European and North American luxury models from the mid-2000s to the early 2010s, including select BMW, Mercedes-Benz, Audi, Volkswagen and Cadillac vehicles. Always confirm that your original bulb is marked D1S or check our Factory HID Bulb Guide before ordering.
If your current D1S lights are flickering, slow to ignite or have different colour temperatures left and right, replace both bulbs as a pair and inspect the ballast at the same time. Use this collection to find single D1S bulbs, paired bulb sets, replacement ballasts and full D1S headlight kits. Our ballasts are universal units that accept a single 12V input and can be wired to almost any vehicle when retrofitting or repairing an HID system.
