1994 Civic DX. Last week on the way to work, thought I saw the headlights flicker but it was so fast, thought it might just be me. A few days later, switching from Hi Beam to Low Beams, the Low Beams would just shut off for a second, then pop back on. After driving for a while with the Low Beams on, they would occasionally shut off for a second, and then pop back on.

Problem being very intermittent (can't replicate when I try to), its probably going to be frustrating to troubleshoot. I see each headlight has its own ground, and gets power from separate fuses. Looks like the first place in line where they are joined (since they both drop off at once) is the switch in the column. Dash lights stay on, and as far as I know, so does everything else. (can't see tail lights while driving obviously)

Where would be the first place I should start looking?
