So I went around looking through forums and such and many recommend the Sylvania osram bulbs if you were replacing oem bulbs. So I got them to compare to the deautokey ones.
My garage wall is gray and camera doesn't truly get the color but you can tell the difference.
This is at startup car is off.
Here is after 2min and the car is on bulbs now fully warmed up
You can see the osram on the left is more yellow than the deautokey on the right. As far as brightness goes they are equal if not deautokey is a tad brighter. This is their 5500k color. In person the color is pure white with a hint of blue. Way better than oem imo
Don't mind the dirty headlight
So overall I'm very happy with the deautokey set that I bought. And it costs less than the Sylvania osram. Another reason I like them is every other bulb so far has been great and deautokey is an active member on here and backs their product.
Hope this helps
