SinoparcelD1S/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.

OEM quality , It was nice & easy fix on GLE 5 stars product

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

EDITAfter 5 months of use the bulbs stopped working, I suspect heat issue as the vents stopped cooling. The seller gas instantly replaced both bulbs despite my really negative feedback so I am revising it to four stars. The seller never asked me to do it, nor had any other requests.EDITEDIT.After writing my review the seller reached out to me with a proposal to issue a full refund, and asked me if I would agree. I said yes and a day later they said it was a mistake and blamed Amazon, which I am sure has nothing to do with this. Really bad customer service from Sinoparcel./Edit.I have used these bulbs for a month and I don't find them brighter than HID bulbs, not at all. Within 5 meters of the car they are bright enough but when you get further they definitely fade significantly. My headlights are properly aligned by the authorized dealership, so please don't think I have lowered them too much hense my perseption.Also the cut-off line is definitely not that good as with HID bulbs. It feels like you have been using a torch that is not properly focused.Regarding the light color- it is proper white, not yellowish, not blueish, a bit more on the cold side but not irritating.I can not comment on longetivity as the manufacturer's claim for 30 000 hours would definitely outlive my car. Installation was as easy as "just replace the old HID" and no additional job required. Package and build quality seem good.To finish, It works fine but definitely does not compare to HID quality.

Not very good. Only bought in Nov and already it's not working properly. Have to turn the lights off and then on again.

Bought these d1s bulbs a few month ago had no problems at all apart from fitting they are a little bigger than original bulbs but managed to squeeze them in, they are really bright but aren’t blinding to other drivers, visibility is improved so much they are as bright as Audi led headlights, they don’t flicker and they don’t show up any warning on 2009 insignia and are at a good price when some other bulbs are over £100 but would definitely buy again from this brand very impressed

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

One of my OEM bulbs failed. I decided to use this opportunity to get brighter bulbs and these came about.They were easy to fit to my BMW 5 Series F10.They were an improvement on my OEM (probably 4300K or 5000K) in that they provided a brighter and obvious whiter light.The quality looked as good as the Osram OEM I removed.Unfortunately in less than 3 weeks one has failed completely. I ask myself had I fitted it correctly or the connection was poor but after removing the access covers all looked as it should. The bulb had just appeared to have failed.I believe I got less than 8 hours use out of that one bulb.The other side is still functioning so I have temporarily put one OEM bulb back in and ordered some LED upgrades. I hope I’ve not wasted my money further now!I’d not recommend these in my limited experience of them.
