I need help figuring out why my front right turn signal loses almost all power when I turn the headlights on. The signal flashes very dimly when the headlights are on and normal brightness when the headlights are off. The back turn signal is fine and the left side is fine. Just started happening whithin the past month. Thanks for any help.

Remove the bulb and check the socket.

Also, click on the link in my signature and see Tip 3. That shows a connector that could be part of the problem.
