Review on D1S 35W 6000K Xenon HID Headlight Replacement Bulbs (2 Pack) by Charles Thomas

After ten years, one of the factory HID bulbs in my car began to turn "pink", and I am sure the other one was not giving 100% light output since HIDs fade with age. Instead of going with the factory 4500K color bulbs, I decided I wanted something more white, closer to how modern LED headlights appear, but without looking blue. I chose these in the 6000K color offering.Bulbs on modern cars are not easy to replace, and HIDs are especially difficult. Of course this is not the fault of the bulb manufacturer, but the car maker. Also, care must be taken to be 100% certain that the circuit is off and cannot come on automatically. HIDs use an ultra-high voltage supply that can be deadly. Despite those challenges, these bulbs went right in place, just like the original factory equipment. They provide great light output and the color is perfect.My car is "pavement colored" which seems to make is practically invisible to other drivers, so I have my headlights set to come on all the time when driving. So far, these bulbs are performing well, but only time will tell if they will last ten years like the factory bulbs.
