I have installed them in a Golf 7 with a very cheap Chinese T10 bulb, it caused a malfunction. With a branded T10 bulb, it works perfectly fine!

It does not work on cars K for license plate lights. The check lightbulbs indicator still lit up even after installing the resistors. Also, the connection of the bulbs did not make good contact with the ceiling light, so even if it worked, there would be an issue in the rain
