Can you replace LED in Rear Light Cluster

[balu29]

Hi wondering if its possible to replace the led lamp in a A1 rear light cluster? the light has been faulty and on checking the wiring block it looked like bad contacts. wiring now repaired but light is still faulty. on swapping the rear light with the other side the light is still faulty. Brake light and others are still working just the main light thats faulty.

Thanks for any help

Generally if it's led then it's not replaceable OEM path anyway, usually need a new unit or used.

Thanks for confirming.
I have now got a replacement light which is fitted and sorted the problem.
However now neither reverse lights is working. Now I can't be sure they were working before and as these are not led bulbs am now confused. One side is showing 5.7 volts all the time while other side is showing no voltage. Both bulbs are fine. Wondering if it may be the reversing light switch faulty or wiring at that end?
