Question on rear light (when unlocking car)

[Hans_ACS]

Just a question : until yesterday, my rear lights lit up when I unlocked the car (together with the blue leds under the door handles). As of this morning, the rear lights are not being lit, just the leds under the door handles.

What is the normal situation here ? How are guys rear lights acting when opening the car ? I thought it was a cool feature ...

Thanks for the input!
