Sinoparcel D4S Xenon Bulb, 8000K White, 35W 3600LM, Whiter & Brighter D4S Headlight Bulb, Suitable for 66440 66440CBI 66440XN2 42402 42402XV2C1, Pack of 2

Very bright compared to the original ds2 xenon bulbs I had previously. Highly recommend especially for that price 👍

Brilliant bulbs. very bright and gives nice white light. easy to fit and that even provides a pair of gloves, so you don't get any grease off your fingers on the bulb.

I bought these for a 1st generation (2011) Volvo XC60 when one of the old bulbs had gone a dull purple colour. I had done the usual thing of checking Halfords and Euro car parts but was shocked to see the cheapest D1S for over £50 each from established brands. I knew that it was advisable to replace both at the same time and really didn't want to fork out over £100 on bulbs. I found these and decided to give them a go based upon the number of positive reviews. They took about 5 minutes to fit and I am really pleased! I bought the 6000K version because I didn't want them to be too blue, these are perfect! The light has a slightly blue tint which makes the car look more modern and they are brighter than the old bulbs too. Like most other reviewers, I've only had them for about a week so far so I can't comment on longevity but even if I got a year out of them, at £21 a pair, they are 5 times cheaper than the cheapest leading brand and seem to perform equally as well. *Update - 17/08/2024* One of the two bulbs has now failed completely so in total they have lasted 9 months before needing to be replaced again. May buy another set for the price as one of the two is still working. It is a Volvo so the bulbs are basically on all of the time when driving day or night so they have probably had twice as much use as they would have had in a normal car. *Update - 12/09/2024* The other bulb has now started to flicker. I contacted Sinoparcel regarding the two year warranty using the email address in the instruction manual and they were really responsive and apologetic. I sent them proof of purchase (a screenshot of the order off Amazon) a photo of the front of the car and a photo of the bulb fault on the dash and they are sending a new set out to me which should be here in the next 4 days. They haven't asked for the old ones to be returned. *Update - 14/09/2024* The new bulbs arrived packaged from Amazon via our usual delivery driver two days earlier than expected. Now fitted and working well. I was so pleased I also bought another set to keep as spares in the boot.

Cool white and good projection. But the build quality is average.lets see how long they last. Good value for what they are.

Do not buy these no light at all in the dark

Perfect fit for my Audi A6 2015. I bought them back in 2023 and one bulb died exactly 3 years later! Changed both of them now in 2026. Very bright and nothing to complain about. Happy with my purchase and I am a returning customer.

Verry good

Great price, easy to install, very good brightness. Had a bulb failure after 14 months though, so within the 2 year warranty. Seems impossible to get in contact with this supplier. The contact us/support form on their website (at the time of this review) does not work, so I've marked the score down on this basis.

Fanno una bella luce . Finora dopo 2 mesi di utilizzo sono soddisfatto

I installed these on a 2009 BMW 335 to replace the OEM headlight bulbs. Install is pretty straightforward and not very difficult (lots of videos online that walk you through the process). I ordered the 6000k version and they are very bright and mostly white tint (with just a tinge of blue). They are much brighter than the OEM ones, which were more of a yellow, especially towards their end of life. I have had no issues with flickering or anything else and they are much less expensive than the OEM bulbs. Will update if I have any issues but so far I am very impressed and highly recommend. ***********Jan 2025 Update ****************** My passenger side bulb is out now. It lasted over 2 years and had zero issues during that period. Unfortunately it is past the 2 year warranty period or I would try and see how the company handles this. The driver's side is still going strong. I will purchase another set again because I still think they are worth the price and not too difficult to install. ******************************************

Buena calidad y mejor precio

Funcionan a la perfección

Went to four different auto parts stores and all of them wanted over $100 for a single one of these bulbs. I was elated to find two of them for less than $30 here. They came with gloves because apparently you have to be really careful with the electricity when installing, but installation was doable, I appreciated the gloves they came with, and they were great! Truly epic value!
