Headlight noise?

My 93 C4 has been sitting for a little over a month and I just checked and found the battery is completely dead. Hooked up the charger and a clicking sound started coming from both headlights. You can see the manual knob trying to move. The headlight switch is in the off position. What could cause this? I disconnected the headlight wire harness and am charging the battery now.

Low voltage will cause all sorts of electrical issues. The relays are likely freaking out.

Get it charged and you'll be back to normal.

Thanks, never heard this noise out of it before. Just got this in October so I'm a newby at Vettes.
