It does kind of matter
Because one is easier than the other
(i think)
Having no switch and just putting a piece of paper in between the battery and the wire would be easier but a bit annoying (having too take off the body if you want to use the lights.......)
But having a switch (i think) is a bit harder, since you have to wire some wires to the battery. But you wouldnt have to take off the body when you wanted the lights on..... But there would be a switch on your car somewhere.......
So it would matter because with your ratings i just wasnt sure whether you meant headlights and taillights with a switch......
