Philips D1S Xenon HID HeadLight Bulb, 1-Pack is rated 4.2 out of 5 by 9.
Rated 5 out of 5 by from Works great! Replaced a pair of D1S bulbs on a BMW 335i. (the originals on the car were German OSRAMs, 4300k) A few notes: Don't wait for the light to go pink before changing the bulbs. Xenon HID bulbs have a service life of ~2000-3000 hrs, but reach about 75% brightness level at about 1500 hrs. Provided you drive your car for 1 hour a night on average, your cars headlights could be at 60 or 50% brightness when the vehicle is 5 years old! At the end of the service life of an HID bulb, its brightness can be lower than that of a halogen one. Look at lumens AND color temperature. Many people assume that a higher color temperature (say, 6000k) denotes greater brightness, when in actuality, it just indicates a shift in color distribution. Xenon HID bulbs have the brightest output at 4300k, falling as color temperature rises. I recommend keeping between 4300 and 5000k. Note, the higher the color temperature, the shorter the wavelength of the light and the greater light dispersion (read: blinding other drivers). Buy OEM bulbs with thoriated tungsten electrodes for greater stability and consistency in light output. When first installing the bulbs, there may be a yellow tinge. Do not be alarmed. Through the first 100 hours, the electrodes wear in, the color temperature shifts to a more natural 4300k, and the brightness increases somewhat.
