FeaturesDirect replacement compatible with BMW Alpina B6 OEM HID headlight bulbs.OEM-grade, high-output bulbs.Perfect alignment, with easy installation.True colors, with no variance. OverviewUpgrade. If your vehicle is equipped with HID, these are a perfect direct replacement. Since HID bulbs lose brightness after just a few months of use, these will provide a nice increase in output. You can also improve your vehicle's styling with a cooler color temperature. Quality. There are all kinds of HID bulbs on the market, but these are the best combination of quality, without a high price tag. Manufactured in a fully automated environment, they have high output, and are DOT/SAE and ECE compliant in arc position and size. Using German quartz and American salts, no expense is spared in their construction. This leads to a long, reliable life, and excellent color.Color. While some HIDs on the market give off a green or purple tint, these bulbs will provide a pure white color on the road. These HIDs are available in true, accurate color temperatures, which we measure at our photometric test lab. The white color created by these bulbs will provide more visible light on the road, and won't cause distraction.Experience.
