Evening all

I am currently busy with a inspection on a house that was build in 1974 and I came across a light in the garage that is getting supply from a socket outlet. So my question is do I disconnect the light from the socket outlet circuit or would it be suitable to attach a warning notice at the light switch stating it's supplied from socket circuit and also attach a label "mix circuit" on the DB below the plug circuit it is fed from. The installation complies with the general safety principles except +- 6 lights in the house that's wired with ripcord.
Your inputs will be much appreciated.
