seems my car is D1S 85410 6000K
which better 6000K or 4300K? which is more powerfull?

The light output will be the same - the 6000K bulbs will show a more blue color which could lead some to feel they are 'brighter'.

"Kelvin (K) A basic unit of thermodynamic temperature (color temperature) used to measure the whiteness of the light output. The higher the number is, the whiter the light is. When over 5000K the light begins to turn to blue as daylight."

If you want to compare "brightness" you need to look for the "Lumen (lm)" rating: "The international unit (SI) of luminous flux (quality of lights). For example, a dinner candle produces about 12 lumens and a standard 60-watt incandescent bulb produces 830 lumens. The higher the number is, the brighter the light is."

+1 - usually factory OEM is 4300K but I recommend 6000K because you will get the same Lumens output with 6000K as the 4300K but your light will be SLIGHTLY tinted with a whitish blue. Just a better look overall than the white yellowish of the 4300K. They should be D2S bulbs. You have to replace both bulbs at the same time or get bulbs with same life. I have some OEM D2S bulbs from a car I did some work on about 3 weeks ago. They are 4300K OEM bulbs. PM me if interested.

Ahlan min al-urdun. I can sell you both including priority mail shipping from U.S. for $92. The car was 2009 M5 with 18K miles. Assuming the car was driven mostly during the daytime or at least half/half nighttime the lights have about 1 thousand or so hours on them I'd say...so pretty damn new! So pretty much that's $40 a bulb and they list for $212 per bulb!


4300K is the OEM bulb and the brightest.

Yeah... I disagree with the 6000k being same lumen output as 4300k. For example, a D2S Philips bulb at 4300k outputs at 3200 lumens. An average 6000k bulb will output anywhere between 2800-3000 lumens. Depending on your road conditions and visual perspective, but I think plenty of people would say that's a noticeable difference.

Agree, all of these cars, Audi, Porsche, Acura, Lexus, BMW, Infiniti Benz etc...they all use 4300K bulbs for a reason. But some studies show little diffference in Lumen between the 4300K and the 6000K but to be safe go with OEM and you'll definitely get the highest output of proven lumens vs. taking a chance with getting a 6000K bulb with 3000-3200 lumen

I don't think there's anything wrong with the bulbs. Xenon's don't go much dimmer over their lifetime as they wear out. Their colour output WILL change over time, but their light output won't change much. When the time comes, they will just refuse to switch on.

I think it's probably your headlight alignment that's off, and because you have xenon headlights, by law they are required to self-level.

You can check if the self calibration is working by rotating the light switch max to the right, switching the ignition on, and checking (while sitting in the driver's seat) if the light beam moves down and up the very moment you switch the ignition to position II. (you might need to park in front of a wall if doing this in the day time due to lack of visibility, alternatively, do this at night.

Also, do this: (at night) Put light switch to Automatic position, start engine and see if green light next to light switch is either blinking or steady. If it's blinking, it usually means your adaptive headlights aren't working properly ? by the same logic I would expect that if the start-up calibration isn't working properly, the same would blink as well.

Sorry dude, that's incorrect. Xenon bulbs do lose intensity over time as well. Look it up.

+1 - very technical analysis though. lol
