Philips X-tremeVision 85415XVS2 Xenon headlight bulb D1S, set of 2

The result is unreal, it feels at least 50% more brighter and I can notice at least 25% more road being lit up properly. You probably thinking this is another fake review but let me start the whole story.My car, a 2012 year Mercedes E350 with xenon lights, one is showing blue colour and one is showing yellow. I am pretty sure they are the stock ones from factory and has not being change in the past 8 years. I will not be changing them and thought they'd last forever but I was so wrong. I literally have spend hours and hours to study and understand the xenon bulbs, which I should have done in my uni days. The conclusion is, regardless they called, ultimately they are light bulbs and they do fade over the years. With chemical deposites built up within the chamber and cause burn to the glass, reducing the light output. If left un-checked and they will explode one day, taking your light cluster with it to the bin, potentially cause serious injury. Search on internet and you will find all the horry stories, peoples with exploded xenons.The installtion is not the easiest nor the hardest I have ever done but this depends on your card and your skills. I have followed all the requirement of dusting off all the work area and wear gloves, also avoid contact with any glass and ceramic part of the light bulb during installation.Scary. When I took my old bulbs carefully out, guess what I found? Both my old D1s xenon light bulbs had hairline crack on the glass! Further more the glass of inner chamber are really cloudy and covered in crystalised deposite(some say it is salt within the filled air), some burnt area looks like going to crack the inner chamber in the next second. I was so worried that I literally holding two D1s grenade. But in otherhand I was so lucky to discover this before it cause thousands of pounds of repair bill from Mercedes if they were to exlode and taking my light cluster with them together.Shipping time if you interested. I made my purchase here and waited 3 days with my Prime membership. Turns out it came from Amazon EU warehouse. Maybe Amazon should be more pecific about UK or EU stock.Philips and its rival brand(not to be named) are the only automotive bulbs I buy over the years, it is my personal preference but you know when you choose these brand you are in safe hands. This particular Philips D1S seems the right one for my car and myself.

Brilliant product, well worth the money, made a great improvement

Super bright white light. First night drive was a little troublesome, they were blinding oncoming cars so I had to have the headlight pattern lowered slightly. Perfect now though.

One of the xenon’s blew and was showing a pink colour, after much research found these for a good price. Installation was very easy.I find these bulb are bright than what I had before and illuminate the road at night by about 50% more.

Used bulbs received. Found it during replacement, failed to check on delivery ( Very sad...

Yes I found the made a decent increase in the amount of light and more white light which helps.

I had the choice between Osram, Philips or the rest of the HID lamps out there and i chose Philips. Why? I felt that the marketing claims were more accurate and more accurately defined than the osram claims. Without a direct comparison i then had to establish that if i was happy with the Philips x-treme vision lamps.....what made that so? The answer was RENEWED SAFETY.Without realising i had adjusted my driving incrementally as my lights had gradually dimmed. It wasn't that it felt unsafe or was noticeably darker but one of the HID lamps gave off a pinkish hue as i parked behind a car and that evening i did my research. After fitting, i was returning home via a dark road that i am familiar with and immediately noticed the difference. It didn't encourage me to drive quicker because i could see further, it just felt reassuring in the way that it felt before. It reminded me why i love my Volvo XC70....again.

Brought to replace in my Seat Leon.Bright bulbs, worth the money.
