(Golf mk7)
They were installed in the headlights. They don't produce any errors and illuminate incredibly well. I also changed the middle scale with another brand, but when I turn on the headlights, the entire lighting changes with these specific ones. Perfect color, flawless illumination, what else can you say about Phillips. PS The installation lasted 4-5 minutes for both headlights together!

For fog, I don't know, but for turn lights it is excellent & with intense illumination, no comparison to the regular ones.

Strong, awesome build quality but NOT suitable for fog lights, they are only for show. In mountain climbing with fog, they are simply useless, there only 3000k yellow does the job.

They were installed on a 2019 VW POLO. The fog lights were installed without difficulty and without errors. They are very good in terms of their brightness, they really make a difference compared to the factory ones, and the color is a clean white.
