You can replace a broken lamp without removing the signal..

…since the signal lamp socket is located in the hole in the rear shelf, behind the trunk light.
To access the additional brake light bulb, open the trunk.
Inside the trunk, through the hole in the rear shelf..

…turn the lamp holder counterclockwise and remove the holder with the lamp from the signal housing.
Pressing on the lamp, we turn it counterclockwise until it stops..

…and we take the lamp out of the socket.
We install the new P21W lamp in the reverse order.
