Need a direct replacement for your D1S HID headlight? This OSRAM XENARC bulb is the genuine article, made in Germany. It's a 4300K color temperature, which is that pure, bright white light (not the blue-ish tint of higher Kelvin bulbs). It's 35W, 85V, and puts out 3200 lumens. This is an OEM-style bulb, so it should work perfectly if your car originally uses D1S bulbs. Important: Make sure your vehicle uses D1S, not D3S or halogen – they're not interchangeable. Also, HID bulbs change color slightly over time, so a new one might look a bit warmer next to your old one. For the best results, it's smart to replace both bulbs at the same time. DOT approved and built to last. A reliable, high-quality upgrade to keep your nighttime driving safe and clear.
