and my stern/anchor light is way to tall and wont fit in under my rod racks I have mounted in my shop. So I went to WM and picked up a new Attwood Stern light and plugged it in,it will not work in the plug. I notice that the plug in the boat has 2 pins and a hole where it looks like a 3rd pin may have been. I pulled the plug out and it only has 2 wires feeding the light. The Attwood light has3 brass connectors (holes) in the bottom of the light. Anyone got any insight to what or why this light will not work ? do I need a new plug for the boat ? do I need to look for a different light. Also, I move the front light (red and green) to the back in it works just as it does in the front. Im confused
