I suggest you do some research as you could be driving your car around illegally. Thus you might void insurance claims if any.

there is a document on here you an read.
Also the tyres on your motor may not be Etype approved... again illegal in the UK.
I am not sure of all the requirements though... but you should not have had an MOT issued without a rear fog light installed by a professional.
