I have a 2001 Sonata and both the brake and charging light turn on and
off together intermittently (every few minutes). When it happens I hear
a small click (almost like a turning signal sound, but only once and
much fainter).

Also, if I do actually turn the parking brake on, the light becomes
brighter. So I am guessing it is not an actual parking brake problem.

Does anybody know what it could be? And is it serious?

I just noticed that when the brake/charging light turn on my daytime
running lights turn off, but not my headlights (it they are on).

Sounds like alternator or bad engine ground...
possible bad battery...but probably not the battery.

99% chance you need an alternator.
