MBZ 2012 E350 Coupe - I don't think they are LED (its 2012) but I am not sure.
I got these two messages
Check left tail and brake lamp
Check left reverse lamp

They are both out, my question is are there two lamps or one lamp that serves both functions?

Thanks,

Best to pull codes. DIY without codes open duct @ left trunk hinge, check harness if fine, move to connections @ both outer & inner tail lamps. All fine, “may” need to replace inner tail lamp (trunk lid) part # 2078200364 reasoning, it contains both brake & backup.

Thank you so much, it’s the one on the trunk lid, I assume it’s just one bulb for both.
I just wasn’t sure if it is LED or not, watching YouTube, it shows both LED and just a light bulb.

it actually is the whole inner left rear
