Tail light

[Boos2006]

Hi Guys, I have a 2005 X5 4.4 lit and I am having a annoying problem with tail light . Once in every few days I see message saying check tail light / check Brake lights.

I have checked there is no issue with the bulb holder or with light bulbs .I have moved them around just to make sure.

It is always rear right side tail light bulb which seems to be not working. I also checked wiring to ensure they are properly secure , there is indication of any wire issue of loose connection.

Is there a fuse I can check? I am not sure what else I can look for?

Any help is appreciated .Thanks in advance.
