OSRAM XENARC ORIGINAL D1S HID Xenon discharge bulb, discharge lamp, OEM quality OEM, 66140, folding carton box (1 unit)

I bought the D1S version for my 2007 Volvo S80. These bulbs are a great colour of white and look fantastic at night with a great beam pattern. Volvo headlights were easy to take out of the S80. Took about 10 minutes per light to change out old bulbs and install new bulbs. Best to change both bulbs at the same time and keep older one (s) as a spare just in case. Great price at £34 each too. Don’t go to the main dealer to have this done, save your money and time and do it yourself!

It's too early to tell if these will last, but the fitting experience on a BMW 420 F36 has been good. As others have said the bulbs have a slightly warmer hue than the outgoing/failed Philips but the brightness is great and I have now replaced both sides. Replacement was the easiest job on any car I have owned (prob 10 min max) and after the manual saying "main dealer job" I was initially hesitant to give it a go. I just turned wheel to full lock to give maximum access into the wheel arch, unclip small cover in the wheel arch and a cover on the back of the headlight rotates off. Lots of videos you know where help in this matter. Top job, fortune saved, very happy.

Great quality bulb, was a like for like replacement. Pretty straight forward to swap out. Would recommend.

Noticed that one of headlights had recently turned pink when I looked back in a multi storey car park. It then failed completely only a few days later. Wanted to replace with a trusted brand and retain the original colour temperature of the headlights which is around 4300 - 4500 Kelvin for best overall night visibility as higher colour temps look whiter but are not necessarily as good for actual night vision. Ordered these Osram Original Xenarc D1S 66140 with the hope that they would be the same as the Mercedes Benz dealer bulbs and low and behold when I removed the cover to replace the original lamp I was greeted with exactly the same Osram 66140 lamp already in place! Now credit must go to Osram as these are the ORIGINAL lamps fitted to the car so that's a very good lifespan.. After looking online I was a bit worried that the replacement process might be a bit torturous but in the end it was very straightforward as I am fortunate to have the access panels with a small thumb turn release, built into the wheel arch liners so really all you need to do is raise the car on the jack to improve the clearance and access the lamps. (It's probably possible to do this without raising the car but it's a bit tight) A quarter turn of the round cover inside reveals the back of the lamp which is easily removed with another quarter turn and the cable disconnects by pressing the small metal clip. Be careful not to touch the new lamp with your fingers as it will shorten the lifespan. There is a plastic ring that unclips from around the buib that you reuse on the new one. Just make sure the small lugs engage in the same place as the original and you're ready to refit the lamp with the same quarter turn. Refit the round cover to seal the headlight against any dirt from the wheel arch . All in all quite easy to do at a massive saving over main dealer cost and the initial impression is better light output than the old lamps. (Follow up: after a three hour night drive and the new lamps are clearly better than the old, main beam in particular, so I should have changed them sooner just as a matter of course)

Cheaper than some Seem to work perfectly well so far

Buy good quality and you won't regret it. I've purchased cheaper Chinese bulbs and they don't last or are faulty.

Fitted my BMW e93 great.

Perfect. Exact colour and tone of the bulb that it replaced. It worked and the price was good.

Lamparas xenon de calidad reconocida para sustituir por las de origen después de 18 años y montón de horas de servicio. Sustituidas sin problema y funcionando impecable.

If you have a Porsche Cayenne 958 generation - (2010-2014) then this is the exact original part to use as replacement bulb for the vehicle. Osram is the OEM supplier of this bulb to Porsche. If you buy this bulb from Porsche Dealership, it is the exact same product as this from Osram...... except it will be triple the price in the Porsche Box. This is identical to OEM.

Arrived on time . Perfect fit and quality

wymiana w aucie bez żadnych trudności, działają idealnie, światło jest ładnie odcięte i równomierne w swojej wiązce (nie ma obszarów znacząco jaśniejszych i ciemniejszych), jasność i przede wszystkim kontrast jest bardzo dobry. Nie wali jak laser z gwiezdnych wojen lub ledy z aliexpresu od których po nocnej jeździe autem dojrzewa żyto na polach. Auto nie zgłasza żadnych obiekcji co do żarówek.
