Review on D3S D3R OEM HID Xenon Headlight Bulb Replacement: Crystal White, 35W, 6000K - Pack of 2 by Audrey Caldwell

Dealers and auto shops were offering me $115-300 for a bulb while a pair was $27. Needless to say I was concerned about the quality at this price but figured $27 wasn't a huge loss if they didn't work. Audi A4 with Allen key, zips for sorting removed screws and flashlight. Took 1 hour but would probably take 20 minutes for those who know what they are doing. Never touch the bulb with your bare hands - the oil on your fingers will ruin the bulb immediately or shortly thereafter. Hold the metal part of the base. 3 months later the lights have helped me get through blizzard, rain and everyday use without the hiccups and they are as bright as the factory lights. 100% recommended!
