I just changed out my old banged up tail lights to a newer set, same style. Its a dump truck. Now, on my dash board, these lights are on. My brake lights work as they are suppose to. Did I miss a ground or is there a poor ground somewhere. I did have to take out the grinder to get good solid raw metal for some grounds. But I'm pretty sure I took care of everything.

Any suggestions...?

Thanks

 

Just to clarify, were they off before you changed the lights out?

 

You didn't hit any of the abs wiring with the grinder did you? Just an idea.
