How hard to change rear indicator bulbs, As just failed MOT as wrong Colour 
Seat garage in Swindon just called me saying my LC just failed its MOT as indicator lights are wrong colour.
How has its passed its MOT at ever other bloody garage then? They want to charge me £38 to change them.
It cant be that hard to change them can it? I have done the fronts but not the rear is it relatively simple and accessible?
Cheers
