Interior LED dome light will not completely switch off

Hello!

I've just installed LED dome light from superskoda.com which they claim do not require a resistor.

The lights turn on fine when I unlock the car, but when I lock it they dim down and will not switch off. Been like this for two hours now and I had to turn them off manually.

The switches are in position for "only when car doors are opened". I've tried to turn on and off the rear mirror dimming (someone tipped about that) without any effect.

In the pictures you can see how the lights are when the car is locked. The regular lightbulbs switches off completely, but not the new LEDs.

Any tip?
