Own W205 Mercedes 2015 c class Two questions please
from the picture below highlighted in red. I need to replace the ambient LED as one stopped working. This is ambient coloured LED





1) what LED bulb do I need? And from where can I buy this?
2) how do I replace this bulb?

thanks

You will need to take the unit apart, as you may not be able to replace those.

Does your handbook list the lamp replacement?
Try your dealership? It may not be a simple "swap out" replacement.
