Iv'e got an 01' Accord and the driver's side headlight always has condensation on the inside of the plastic lens. I have noticed this problem on a lot of Accords..any ideas on how to remedy this???

There's got to be a broken seal around the edges that is letting in water. Got to pull out the head light fixture and reseal around the edges with silcone or some other flexible sealant. If there is a crack in front, you might try epoxy.
