Trunk brake light issues

[Jstrickl]

Hello, my 89 gl1500 brake light and running light are backwards on right side of trunk. At same time on left side running is on till brakes activate and then goes out completely. While saddlebag lights are all good either way. I did check voltage on left side socket and have 11.8 with engine off.

Bad ground circuit. Check the green ground wire to the lights. It is probably broken somewhere and the system seeks ground from another source so it grounds through the other side light which makes the high intensity element illuminate.

You are correct, I forget to check ground Sometimes. That was spot on thank you very much
