I have read alot here about the troubles that people seem to have with their trailer lights. Most of them are due to faulty grounding. My trailer has the ground from the connector going to the trailer. Each light is then grounded to the trailer. I thought that the ground wire should be run to each light. Or should you do both just in case one fails?<br />What is the proper grounding for the lights?<br /><br />Thanks<br /><br />Mike
