Default Electrical issue

Howdy. I have a 2004 Suburban which has developed a weird electrical issue.

When I indicate left, the left turn signal flashes fine front and rear, but so does the right tail light and the front left side marker. This only happens when the headlights are off. When they are on, everything works as it should.

It seems like a bad ground or a short to me, but I was wondering if it was a common problem with a known cause?

Bad ground I agree.
