The headlights are on high beam but the low.

The headlights are on high beam but the low beams are not on. I replaced the colum switch and verified that the dimmer switch is working but still no low beams high beam indicator still on high beam. I have checked everything I can think of but still no power to the low beams and the high beams are not very bright. Any ideas? I'm really frustrated I have spent many hours.
