small rear lights quick question

Can someone just confirm with me that the light with the reflector on it is the tail lights and the one underneath that the brake light?
Its just im removing the crystal M3 style ones to put standard back on and just wanted to put them back right!
Also are the small rear lights the same as convertible rear lights?
Thanks

 i had the same dilema mate when i removed my crystal ones!!, the marker/side light is the top lamp behind the reflector part, and the bottom one is the brake lamp, i think all the early small lamps are same as cabrio ones except the really early ones which had no reverse lamp part
