So my wife tells me my right brake light and turn signal isn't working. She was behind me so I turn on my lights and the tail light works. When I unlock the truck the lights come on and flash brighter and the Hazzard lights work just fine also.
Could this be a wiring problem or just a bad LED?
I check my lights about once a week when I pull into work using the reflection in the windows and they were working fine Thursday.

 

Start simple check the fuses

 

Not sure what the problem was. Fuse was good, bulb was tight and couldn't find a loose wire. It works fine now.

 

Might have been a lose connector, or dirty one.
