Anything special for grounding running lights?

Thank you all. I took the grill off again and looked at it and found some spots that were too nicely painted. I scuffed it up a bit and added star washers on 2 of the 4 bolts holding the grill to the sheetmetal panel behind it. I also realized that there is another piece the lights bolt on to that is riveted to the grill. I took those rivets out, scuffed the metal up good, and put it back together with small bolts, nuts, and star washers. Should be good now. Battery was dead so it's charging and I'll check it tomorrow.
