Last night on the way home from school I noticed my left headlight flickering. When I stopped for gas, I went to check the bulb and harness. Now I already know the harness won't lock onto the bulb, so I thought that might have been the problem, But the problem seems like the harness has a loose connection. When I move or touch the harness a certain way the light flickers.

What are my options... Can I fix/rebuild the harness in anyway, It looks like it can come apart(It also looks greasy inside)?
Should I replace the harness... How hard is that? I saw this in the General Discussions and was thinking about tring upgraded harnesses.Upgraded Harnesses

Has anyone had a problem with their harnesses, not from melting, just wearing out?

Thanks
Robert
