Simple DIY Underwater Fishing Lights
I was scrolling around on Facebook one day and came across a post by Karl Bruning showing how he made a under water LED light’s. All you need is about 10-15 feet of flexible LED light strip, a waterproof container that’s big enough to fit a small 12 volt battery, like this one. It would probably be smart to get an in-line fuse to use also. One thing Karl, didn’t have but I thought might be a good addition to this project, is a waterproof switch Then, the only other thing you would need to get is a rope to send the light box to the depths that you would like.
All Karl did was take the light strip, connect it to the battery, the proceed to wrap the light strip around the battery. You might need to add some sort of padding to the box to keep the battery and lights from sliding around. If you get the same size waterproof box and battery in the description it should sink with out need to add more weight.
