Sinoparcel D1S/D1R Xenon Bulb -2 Years Warranty- 35W 85V 8000K HID Headlight Replacement -Discharge Lamp -Pack of 2-Compatible with 66144 66140 85140 85415 66140XNL

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.

The housing in the back is about 1mm thicker than the original Xenon bulbs, which made it a bit tricky to get the spring clip back on, especially as the access to the headlight is extremely tight. Everything else is fine. Nice bright light

These arrived very swiftly and at a third of the cost for a pair compared with the Osrams I am very pleased with them. They may not have quite the depth in the beam as the Osram's they replaced (one of those died after 10 years so not grumbling) but the car is a classic, seldom used at night anyway and in terms of value for money, these are great.

Hi, bought these in December 2023. In April 2025 they have started to flicker. Knowing that they have 2 years warranty I have contacted the customer service. They were extremely helpful and they have send a replacement. The bulbs are bright, well made and fit perfectly to Lexus IS300h. Buy them, you won’t regret it and topped up with an excellent customer service you can’t go wrong

Cheap for a reason, both failed after not even being in the car a week! Total waste of money stay away don’t buy

Perfect.I see much more with this then a normal xenon bulbs

It’s been nearly a month since fitted to A7 2012 with original bi-xenon d3s bulbs.Fit is plug and playOutput - not comparable to anything I had so far, including expensive dedicated D3S bulbs.The only worry is how long will these last. So far I can’t complain so if they last as long as any original d3s bulbs - I would be keen to call these one of the best xenon replacement bulbs I ever had. The light is super good.I will only work good on lights with projectors - something to keep in mind.No erros on the dash, no flickering. Looks oem and output is better than anticipated. I decided to buy them based on the existing reviews and so far I am very happy with it.

Perfect fit . Blue light not warm light may need to replace both at the same time . But nonissues with the operation of the bulb .
