It sounds like you have a broken ground. The left side headlamp seems to be finding ground through the right side headlamp, causing it to glow dimly. Check the electrical connectors at both lights, you should use a test light and find that you have power and ground at both connectors. I think you'll find that one of them has no ground (due to a broken wire, usually), once that's repaired, you should be fine.
