It is impossible for corrosion to cause extra draw. So something else
changed when you
plugged and unplugged the lights. Like a wire that was shorting.
In the old days, when the body frame was used as the ground for lights,
all sorts of strange
things could happen when the ground connection was lost due to
corrosion. Less of a problem
now with a separate ground wire for the light sockets. But I still see
cars with strange taillight
behavior. Like when they apply the brakes, one light gets bright and
the other goes out.
Missing ground problems virtually never cause fuses to blow because what
usually happens is that
the current gets routed through another bulb on the same circuit and
then to ground.
Anyway, glad the problem went away.
