I want to make a good lighting system. Here are a few things. I have geartracs on both sides of my kayak. I have a 12V plug so they will need to run off a 12V battery. I also want something similar to a RAM Transducer Arm that I can swivel and move around. Maybe attach a light to the end and have one on both sides that I can move around. I assume PVC is the way to go. Anybody got any good ideas that I have not thought about?
