OK i think you are taking this a little extreme. First off if he has a older S4 he probebly knows something about cars because an s4 isnt a car you to often see a commercial for or see it being the cheapest on some used car lot. Second was that his right front light and his lower left fog light were burned out so i highly doubt there being a electrical problem on both sides like that and for that i call him lazy and im sticking to it im sorry.
