Hello,
I have a xc60 2011 and the led stripe (marking light) is faulty on the rear drive side tail light

I am searching on the internet for weeks, but it seems that is an uncommon issue.
I found almost no mention about this kind of problem.
Some of the LEDs are on an some are burnt.

I have just discovered that it is not replaceable..
Here in Brazil a brand new tail light costs a thousand euro!
​​​​​​
Do you guys know what can be done?
If I remove the tail light, is there any electronic component I can change, test, or replace?
If I pay someone to open the shelf , I can buy new LEDs, diodes, etc. But I don't know the part number, specs.

Can someone help this guy here from Brazil??
Cheers
