Up to 6000K Light Output with High-Contrast Visibility and OSRAM Advanced Xenon Technology Upgrade your vehicle’s lighting appearance 

Designed for drivers seeking a more modern, high-end lighting aesthetic, these 35W xenon bulbs deliver an impressive light effect of up to 6000K while maintaining compatibility with factory D4S projector headlamp systems. Built using OSRAM’s advanced xenon technology, this series focuses on enhanced visual styling and improved color perception compared to standard OEM xenon bulbs. As a direct plug-and-play replacement, this mercury-free pair is ideal for drivers upgrading from factory HID lighting to a more contemporary 6000K color temperature.
