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

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

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.

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.

Excellent quality 6000k light. The bulb is almost identical so It fit like a glove. Love it!

They seemed good build quality, brightness also seemed very good, but one of them stopped working after 3 months of barely being used.

I bought these as a cheap way of finding out if the bulbs were the cause of my headlights going off and on.. It turns out it was just the bulbs but these xenon bulbs have really impressed. They are just as good as the much more expensive brands. A nice white light. The bulbs were well packaged and even came with gloves to handle them. Would recommend !

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.
