OSRAM Xenarc D4S Cool Blue HID Xenon Headlight Bulbs 66440CB 42V 35W Up to 5500K Made in Germany | Pack of 2

The most demanded 5500K HID Xenon bulbs on the market.You won’t be disappointed if you simply replace your old standard HID bulb with Cool Blue Xenon bulbs. Cool Blue has the perfect balance between the color temperature and the brightness.

• Compatibility Notice: This bulb is D4S. Although bases look similar, it will NOT FIT D2S, D2R, or D4R. Please verify your vehicle’s bulb size before purchase.
• Important note: Osram Cool Blue HID bulbs are NOT BLUE light bulbs. Blue-colored light is generally 6500K or above. “Cool Blue” is simply the model name.
• The nature of the HID Xenon bulb is that the color temperature shifts over time, becoming whiter as it ages and eventually turning a bluish color before the end of the bulb's life. However, they also lose brightness in the process. This means a USED 4300K OEM bulb might look whiter than a brand-new Cool Blue (CB) bulb, even though it’s producing less light.
