Osram Sylvania XenArc D1S Xenon HID bulb (single bulb) Part # 66144
Osram Sylvania XenArc D1S Xenon HID bulb (single bulb)
Factory Original Equipment on many new vehicles Osram D1S bulbs have perfect aim and brightness and the high quality and extreme long life you can only get from Osram.
When replacing HID bulbs it is highly recommended that you replace both bulbs. As HID bulbs age they slowly colorshift (change color usually to a more bluish white) and lose brightness. Replacing both bulbs will ensure that they match in color and in brightness. You should keep the old still working bulb as a spare incase you need it in the future.
Sold as a single bulb
