Review: Was easy to replace, nice & bright, no colour difference. - Had a light fail on an Audi Q5, replaced it easily with one of these. It was easy to fit, light failure message on the dash cleared, nice bright white light, can’t notice any difference between this and the light on the other side. Very happy, especially not having to pay garage prices to get it replaced! The bulb came in a small box protected by a strong cardboard sleeve over the bulb inside.
Review: Mercedes Benz E350 Coupe A207/ W212 ILS Replace Original D1S Headlight lamps - 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)
