RCP - D1S4 - (A Pair) D1S/ D1R 4300K Xenon HID Replacement Bulb Factory White Warm White Metal Stents Base Car Headlight Lamps Head Lights 35W

Exceptional quality.. The light is clear bright and has a uniform beam... I couldn't be more Happier

Arrived on time and installed both bulbs immediately. Based on another review about a yellowish hue, I was hesitant to purchase these bulbs. Fortunately they are straight white and project the color tone I was seeking! In regards to reliability....only time will tell. I will update my comments as time progresses. For the price if they lasted 1-2 years I’d be a happy camper. For reference, these were installed on a 2006 Porsche Cayenne Turbo S, where ORM bulbs run $100-$150 per bulb.

I bought these because I fell victim to the notorious Escalade headlight leak. The water burned my bulb and ballast. They are no where near as bright as the OEM osram bulbs were with the factory hella hid ballast. I paired these with some cheap ballasts off Amazon as well. I’m waiting to but new headlight housings before buying oem bulbs and ballasts. (It’s roughly 1800 dollars for both sides) I just did a quick patch job on mine current ones just to get buy ( I put them in the oven at 240 degrees for 10 minutes to separate the lens from the housing and replace the butyl and sealed the house side with some silicone) they are your typical stock warm white bulbs. The look white if you look at them up close. They were super bright the first day or 2 but then they got real dem. Like I said they though they are okay they still get you around but just don’t expect oem brightness. Close to owning them for a month, they are super dim at today one burned out. They would occasionally not want turn on.

I have not installed them yet, but I need to for my Passenger side is out. I am impressed with the packaging. I will review when the install is complete. Update: Installed one today, passenger only 3-16-2019 They work as expected and the install was not too difficult. I think this is a great product at an amazing price. I recommend this to anyone who has the application these are compatible with.

The low beam bulb on my 2005 BMW X5 burned out and at the dealership I was informed, "Ooo, that is the expensive one, it's and HID." Will be $440 to change the bulb, not the headlight, but just the bulb. I thought I would look under the hood see how hard it would be to get to the old bulb and remove it. Expecting something very complicated, instead, I found I needed to simply remove one cover, untwist the bulb, and unplug it from a chord. So finding it simple to access, the next chore was finding a bulb. I looked on various OE and OEM BMW sites and the price for a single bulb was anywhere from $140 to $200. Still far less than what the dealer would charge. However, my son talked me into looking at HID bulbs on Amazon. This sight clearly spelled out the various "K" temperatures for the bulbs, and I was able to choose a pair of HID 4300K bulbs for less than $25 on this site. I thought it was too good to be true, so I bet my son that I would get the bulbs and they would not work. Not only did they work great, but I was very pleasantly surprised to find a complimentary pair of white cloth gloves in the Amazon box with the bulbs (you do not want to get finder oil on high temperature bulbs - they can easily burn out or degrade the lights). So instead of paying $440 for a BMW dealership to change out one single low beam headlamp bulb, I was able to get 2 bulbs for less than $25, and a pair of free cloth gloves for free to help me change out the bulbs. Nothing but 5 stars here.

Great bulbs! Oreilys and Autozone wanted $100 each. I got 2 of these for a quarter the price. Easy 20 minute install. I can’t tell any difference between the stock bulb and the new bulb. Be sure to get the right color. My 2007 Escalade EXT came stock with 4300k bulbs.

Don't forget these need some burn in time when you first start running these for the proper color temp. For the price you cant go wrong. No issues with these.

This is the SECOND time I've ordered these lights, and it will definitely be the last. This round, my D1S lamp failed within six weeks. It went out Friday evening, came back for a bit (ignited most of the time) Saturday, but it was out for good Saturday night. Six weeks! These should last 10 years. This seller does not offer two-year warranty. Going with original OSRAM this time and considering the money and time I will save by just changing the lamp once. On this car, I have to remove the wheel and wheel well liner, so it's not a simple plug and play.
