I consider myself a trailer light expert.(Until today) My gooseneck has four round lights in the back, six clearance lights, $ licenses plate light. All lights work, BUT when I put the hazard lights on and the tail lights, the clearance lights flash VERY slightly. Sitting in the shop it does this. When I drive the trailer it blows the tail light fuse. Where am I getting the blinking in the clearance lights?? Should a four lights flash & have tail lights? Should two flash and two tail light? PLEASE HELP!! THANKS!!!!!!
