Rear lights/bulbs query and error message

[MancAnt]

Hi all,
Yesterday the Wife got into our 2016 plate E220 AMG Premium Line Convertible and said that she had a series of errors appear on the dash reporting
"Right-Hand tail lamp / brake lamp , Left-Hand tail lamp/brake lamp". She also said the indicator lights were quicker quicker normal too. She then got back in it after work and the errors no longer showed. Could this be just a single null issue or do these vehicle models have to have the full rear tail light unit replaced as they are led? I've read mixed comments when googling the issue.
Any replies greatly appreciated

Well the wife locked the car, went into work then came back the same day and the errors issue disappeared. She went and got back into the car again today and the same thing happened again today!! Anyone any ideas at all ? Could it be just one light /bulb issue or something else ?

I’d be looking at a weak battery, most modern cars really hate love voltages

Isn't the indicators flashing faster than usual a sign that the flasher relay has failad? It was years ago on my 968 coupe!

or that a bulb has gone.

or that a bulb has gone.

I was told on another forum that this model is led and a full unit and not bulbs ??? Sorry im not very good with Mercedes and their spec
