Blinker Sometimes Works
 

So I figured my front right side marker light was just out but I notice that sometimes it works. Could it be something else is the issue here? I got new LED ones to replace them but now I am worried that might not be the problem.

Any suggestions?

Bad cable connector.

You mean the connector that the bulb plugs into? Suppose I have to remove the headlight anyway for that and if so the new bulbs should experience the same issue.

How does one replace the connector - or perhaps I can just clean it or it could be loose. I think I have to hack it off anyway to splice in the capacitor for the LED's.
