Review on 🚤 Botepon 2Pcs Boat Kayak Battery Navigation Lights: Ultimate Safety Lights for Boat, Bike, and Pet with 3 Modes by Justin Butler

Definitely not waterproof. I put them on the front of my kayak where my paddle occasionally dripped onto them and after one use there was water inside and the ability to turn the lights on and off was erratic. After I dried it, it still worked. You will see gaps for water to enter. I'll try to seal them with some kind of sealant to make them more waterproof. The light output is pretty good. The on and off switch is easy to use.
