Until then, I had never really paid attention to their existence, but when I saw the VOLVO logo projected under the door of a fellow S60 owner's vehicle, I was told that there were also ones with the Polestar logo, so I got one and replaced it.

It's a simple customization that only requires replacing the original lights. The original lights only shone dimly, but the new lights are bright enough to be seen even during the day, and the logo is clearly visible every time you open the door, reminding you that you replaced them.
