OSRAM Xenarc D3S HID Xenon Headlight Bulbs — Cool Blue 5500K Pack of 2, 35W 3,200 lm Made in Germany

OSRAM Xenarc D3S Cool Blue 66340CB are high-output 35W HID xenon headlight bulbs that deliver a crisp 5,500K white-blue beam and up to 3,200 lumens per bulb for brighter, higher-contrast road illumination.

These premium German-made xenon lamps combine advanced filling technology and OEM-grade manufacturing to create a sharper, cooler-toned light than typical 4,300K stock bulbs. Designed and produced by OSRAM, the Xenarc Cool Blue model aims to give a modern, attention-catching appearance while maintaining lawful on-road use when matched to compatible D3S housings and ballast systems.

How do these bulbs differ from standard xenon or halogen lights?

Compared with halogen bulbs, HID xenon lamps produce far greater brightness and a color temperature that appears whiter and slightly blue. Versus standard 4,300K xenon, the Cool Blue reaches about 5,500K, creating a cooler visual tone and higher perceived contrast without changing the lamp's electrical rating.

• Color temperature: approximately 5,500K for a whiter-blue look
• Light output: roughly 3,200 lumens per bulb (±15%)
• Power rating: 42V / 35W compatible with D3S HID systems
• Designed to be noticeably brighter in appearance than halogen

Will these OSRAM D3S bulbs fit my vehicle and setup?

Fitment depends on your car's factory headlamp system: these bulbs use the D3S base (PK32d-5) and require a compatible xenon ballast and socket. They will not fit D1S or D8S housings even if the base looks similar, so confirm your vehicle's bulb type before ordering.

• Size: D3S with PK32d-5 base—verify your owner's manual or bulb label
• Not compatible with D1S or D8S housings
• Please confirm ballast compatibility for proper ignition and beam control

What performance and longevity can I expect from the Cool Blue 66340CB?

OSRAM rates these bulbs at about 3,000 hours of typical service life under normal conditions, with peak brightness near initial installation. Over time the color characteristics shift and brightness decreases—this is normal for HID technology as the gas composition and electrode wear change with use.

• Rated life: approximately 3,000 hours
• Initial luminous flux: ~3,200 lumens per bulb
• Color shift: spectral tint evolves toward bluer tones as the bulb ages
• Sold as an OEM-grade pack of two with authenticity label

Are OSRAM Xenarc Cool Blue bulbs legal and safe for street use?

These Xenarc D3S lamps are manufactured to meet road-legal standards where HID replacements of the correct type are permitted. Always ensure your headlamp assembly and aim comply with local regulations and that the D3S model is the factory-specified option for your vehicle.

• Manufactured in Germany with an OSRAM authenticity label
• Designed for vehicles that originally use D3S HID bulbs
• Proper installation and aiming are required to meet legal on-road lighting rules

Who is this for: drivers who want a cleaner, cooler-looking xenon beam and OEM-level construction—especially owners of vehicles factory-equipped for D3S HID systems. If you seek a brighter, high-contrast appearance without changing your headlamp housing, and you have confirmed D3S compatibility, the OSRAM Xenarc 66340CB Cool Blue offers a German-made option that blends modern styling with proven xenon performance.
