Philips Automotive Lighting D1S Authentic Xenon HID Headlight Bulb with 4200K Intense White Light, Fits Select High Beam and Low Beam Positions, 1 Pack

Headlight works as it should. And the price is so much more affordable than at the auto shop! Great value and quality!

Cheap and work great

Good quality bulb, it seems to be a little dimmer than what is installed in the other headlamp unit. No issue with flickering as of now, and visibility is adequate for daily driving. Hopefully, the longevity will last years to come.

Item shipped well packaed and on time. Authentic packaging ans item. this fit perfectly in my e46 coupe, restored the brightness my older OEM bulbs had lost over the years. Working perfect so far!

Brightness is not as it says on the listing "Intense White Light" but rather it's more of a yellowed light. Still, I have to blame myself for this buyer's mistake because if you search Google for the measurement of color for light output, you'll see that 4200k is not as "intense of white" as it claims. So a quick Google search would have told me not to believe the intense part of the claim. Oh well.The light on the drivers side (left) is the OEM light which is probably 5000 or 6000k. The one on the right (passenger) is this one. See the difference. I don't like it, but I'm not changing it. I'll leave it in until it burns out as I'm already past the return window.Quoted from Google search results, "Color temperature is a measure in Kelvin that defines the color appearance of the light produced by any source. The range of color temperature goes from warm yellow hues, at low Kelvin values, to cool bluish tones at high values. In vehicle headlighting, the color temperature is more than an aesthetic choice; it is very important in terms of visibility and glare and in general driving safety.Driving at night can make a big difference in your choice of color temperature of the headlights. The warmer light at a lower Kelvin value is easier on the eyes and provides better contrast in bad weather conditions, such as fog, rain, or snow. At a higher Kelvin value, cool light can light up more details when on a clear road but produces glare on wet or reflective surfaces. Understanding color temperature will help in the choice of the right kind of headlight for driving conditions and comfort."We never have ANY precipitation in Phoenix so I don't have to worry about contrast or wet surfaces. I wanted what the car came with, but that's not what this is. It does work, so I have to give it at least 4 stars, but I deducted one because of the *Intense* & *White* wording it erroneously uses.UPDATE: It's been five months since replacing one of the lights on my 2014 Model S. So far the light is still strong & has not flickered its way to being completely off like the old one. I'd been living with that for a whole 2 years, so it was time. I still have that one gripe from before. It's not as white as your old ones from the factory. I've seen on the TMC forums that some people prefer this slightly off-white look to it. Not me. I miss the old OEM factory white straight out of Tesla factories.

Bought two Sunday night (October 25th) and received them today (Wednesday October 28th) using standard FREE shipping. Nice!Looks like the real deal - Philips bulbs- I have no reason to believe otherwise based on packaging and bulb appearance. Great price at almost half of what Auto Parts stores sell these for. They work fine and have the right color - looks good. I'll write a review later if these have issues or fail early.Installation is fairly easy. If you have any sort of mechanical ability --- like changing a faucet washer, changing a household light bulb, handling basic tools, etc. these should not be a problem replacing on your own.Suggestions (2002 Nissan Maxima):1 - Don't touch the actual glass on the bulb... some feel that oil from your hands can significantly reduce its lifetime. Opinions vary because that was the standard rule with halogen (which create a lot of heat). I just didn't want to take a chance.2- You may have to move your battery to access the drivers side light. Not a problem. You don't have to remove it, just move it out of the way. If you have a newer battery, it's probably smaller than OEM (mines smaller) and you don't have to move it at all.3- You don't need any tools to access or remove the bulb. It can all be done by hand.4- The cover turns counter clockwise about 1/8 of a turn to remove.5- The power connector moves slightly less counter clockwise to remove.6 - The little clip that secures the bulb will move back into place after you squeeze it and then remove the bulb. Just lift up and put the new bulb in and squeeze back into place. It moves up and down... it will not fall out.7 -Pay attention to bulb position and replace bulb in the same position.8 - Put everything back in place.9 - Check headlights!10- You're done! Congrats you just saved a couple hundred bucks!THANKS AMAZON!P.S. My car is a 2002. Both bulbs went out within days of each other. I suggest replacing both bulbs at once. HID (Xenon) do not work the same as standard halogen bulbs -- they use a lot of energy and require an ignitor -- the system has a bit more going on and has other components that can fail. I hope if you are having headlight issues the solution is a simple inexpensive one. :-)
