Yeah so we'll have more retards using them AT NIGHT without realising the rear lights don't switch on with DRL's in most cars.
OP : There is no road rule that states lights need to be on at 18:00 exactly, because as seasons change 18:00 isn't really a valid value. What it does say is that lights should be one when the sun has gone down...but people are idiots.
At least you will still be able to see them approaching (so they wont t-bone into your side when you pull off at that intersection into a main road or leave your driveway because you'd have seen them coming) or, and their instrument clusters will show them lights are off and the full beams from behind will make them wake up. And vehicles have reflectors on the back (besides the numberplates) and if you drive into someone, that is moving, from behind you might need to go for eye tests (unless it is a dirty old skedonk, which might not have working or very faint rear lights anyway and very dirty or no reflectors).
