This is a genuine BMW rear light "LED" right side panel, part number 63 21 6 937 450. The number stamped on the part is 63216937450; BMW's catalog files it under the short number 6937450. You will find it on our Lighting shelf, under Rear lights. It supersedes the older number 6920694, so a part carrying that number is the same part.
It fits the E46 coupe (323i, 325i, 328i, 330i and M3, 2000–2006), with the M52, M54, M56 or S54 engines — and the European-market versions.
BMW draws it on the Rear light in the side panel (63_0555) diagram. It weighs about 850 g (1.9 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
