Do the headlights flicker for a moment if it happens at night?

When taking off slowly, I remember my S4 frequently doing an ABS check,
where it'd shudder for a second, you could almost feel it through the
pedal but not quite. There was no rhyme or reason to it, it'd just happen
occasionally and I learned to spot it and recognize it as just.. the way
things were. :P

If this is it, the headlights flicker because it's a pretty hefty sudden
current draw. I seem to recall it did it worse when my battery was nearing
the end of it's life after being run dead a few times. Speaking of
batteries... see my next post.
