D1S HID Bulbs, 6000K Cool White, 150% Lighting Distance, Xenon Bulb, IP67 Design for Replace 66144 66140 85140 85415 85415C1, Pack of 2

The price gave me some pause before my purchase because of how low the price was compared to the OSRAM-- ~$100 for a single bulb. I figured I could replace several times given the price difference. After having used them for almost a year, I can say without reservation, these are great! The lights were a perfect fit on my E90 BMW. The lights are bright and work well-- no flickering.

These headlight sure did surprise me. I have bought my fair share of headlights from Amazon that we're much cheaper than OEM and they always disappointed me. Usually due to dimmer light than OEM and inconsistent lighting pattern that scattered. But with these the pattern of the light is actually very consistent so much so that unless you compare an OEM bulb side by side you can't really tell. Due to the fact they're HID the color does change. It starts out as more of a 7000k color where it's very obviously blue but give it thirty seconds and they cool down to be a simple white that's neither more blue or more yellow as advertised. Theyre almost nearly identical in brightness to OEM if there's any difference they are just the very slightest bit dimmer but after all they are 30$ about 1/5 the price of OEM bulbs. The installation was a pain but that's obviously not due to the bulbs but depends on your car. I have a 2013 Lincoln mks and they fit perfectly. To sum it up these bulbs are cheap true to color fit perfectly and are as bright as OEM.

Several months in and still working great, hopefully they last, they are much brighter than the original headlights. Well packaged, a bit of an install process but that's Ford fault not the bulb. There are plenty YT vids to show you how to get it done.

Easy to install, EXTEREMLY Bright! At night it is like we have the bright's on when we do not. Clear clean light that you can see in the national forest with ease! Great purchase! I would buy again!

Fit 2008 BMW 750Li E65 perfectly. I replaced the OEM bulbs by these. They are very bright, no flickering. Fairly easy to install, just remove the filter box on each side, remove the cover, then twist the light house. Unsure about longevity.

Been using for a few days, super bright and doesn’t blind other drivers. Installation is pretty straight forward ( depending on your car ) Bulbs get super hot to the touch after seconds of being on. These lights will save you a lot of money as D3S are typically very expensive. They fit perfectly on my Mustang, and will order more in the future!

My husband installed these on my 2020 Tahoe. He was able to do it by himself (other than me handing him tools) in about an hour and a half. They work great. Both of my highbeam bulbs had gone out and these are perfect.

They are bright and was a direct swap. The only reason I gave it a 4 is because they only lasted a year. They are fine for the price and never lost brightness. it will take a couple of cycles to reach the full bright white light.

I have had these for two years and they started failing several months ago. The low beams only work intermittently now. That's only about 1.5 years before I needed to replace them. For $73 CAD, that's not good enough. Also, these don't turn on my high beam indicator light on the dash, which isn't a big complaint for me but is worth mentioning. They are way brighter than regular bulbs and I like that but for this price, they should last longer. So I'm going with a different brand this time around.

Perfectas, y me han costado el 20% de lo que me pedían en el concesionario. Compra totalmente recomendada

Drove intercity on a 6 hour night drive yesterday and these bulbs lit the road up like a Christmas tree. Really glad I purchased them.

Satisfecho con la compra. Llegó en buenas condiciones, llevo un mes con estos faros y no he tenido ningún problema. El color es lo que esperaba (blanco ) y alumbran muy bien .

Easy installation on my Skoda Octavia. Came in good packing. Lighting not too different from the stock Philips bulb. Early days, can’t comment on longevity yet.
