Ordered replacement black light boat switch for night fishing. A rocker switch was included because the tip of another switch was broken off by people getting on the boat and getting too close to the gun and breaking off the tip of the switch. It was raining on the boat one night and I noticed that the headlights were partially lit and the switch was wet and shorted. Replaced it with a Qiilu switch and it rained on the boat again but the lights didn't go out and the switch didn't get wet. A simple replacement for another that uses a 3/4 inch hole. Pulled out the old one, connected two cables and plugged in the new one. The exchange lasted about a minute. I now have an extra switch in case something shorts out next time.
