Anyone on here do trailer light repair on the side? I have trailer lights however I have no turn signals or brake lights. I have had the truck checked and according to Ford its fine. someone told me I have a ground issue they might as well have told me I need to learn to speak German. I have no experience with trailer lighting. The boat is in the garage so you wouldn't have to be outside working on it. If you know of anyone or work on them please let me know.
