I installed them on the license plate.
Quite decent compared to the simple yellow T10.
The truth is I expected them to be a little brighter.

The white 4000K W5W (lice) combines the color exactly with the rest of the bulbs (turn signals, headlights) of the Mercedes W211 E200 163PS model. Since they also have a long lifespan, I will buy them again.

For license plate lights that I use, they are slightly whiter than regular T10 ones because the LEDs indicated a burnt-out bulb, so I got these. Now, as for how long they will last, only time will tell.
