Technical Light warning MOT fail?

[GeorgeFiatGP]

Hi guys I've got a bulb warning light on dash, all are working ok, I've cleaned up all the connectors and it's still there, checked number plate bulb that's also ok. I've got mot Thursday, is there anything I'm missing and will this be a mot failure?
Thanks in advance

It failed and I'm stuck with what to do about it

Can you pull a particular fuse short term.....or get OBD reader and put light out?

All sorted, had to rebuilt connection on rear light cluster, bulbs were fine but connector was bit corroded
