Sinoparcel D1S Xenon Bulb, 35W 8000K White D1S HID Headlight Bulb, Replacement for 66140 66144 85410 85415, PK32d-2, Pack of 2

These bulbs are brilliant. Really bright output and a big improvement over the originals on both dipped and full beam. Night driving is much clearer now. On startup they have that slight purple tint for a second before settling into a clean white light, which actually looks pretty cool. No issues so far and they’ve been working spot on. Definitely recommend if you’re after better visibility.

So far it’s work and fit well. Value for money. Beam pattern good as it stated

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.

very good

Good product at less than a quarter of the price the main dealer wanted!!
