I've never had to do this and I have all the right equipment, a set of amber/red lights to replace the orange flags at the widest point. I just can't get the magnetic bases to stick to the fiberglass! LOL!! They are great lights and I've extended the wiring for the 11 foot beam, but I can't think of a way to secure them to the side of the boat. I could duct tape them, but then I'd have an ugly mark that gets dirty quickly. I was trying to figure out some way to use the cleat to hold the light, but I'm just out of ideas. I figured someone has already done this and they can share their method! Pictures get extra bonus points!!
