Audi A3 tail lights

[Aqeel]

Hey guys
I have updated my Audi A3 sportback tail lights to led ones so they hv been working all gd and all of sudden yesterday the right right led went off then I switched it off nd put it back on so it worked for few seconds nd goes off.... I thou I should say rip to the led but When I checked with 12v battery so it worked perfectly but it doesn’t work when I put it on so what it could be....

Loose wiring and/or connectors?
And is it the whole cluster or just one light that doesn’t work.
