Finally a waterproof (to 3ft.!!) connector that you don't have to cut to disconnect. I used to make three OGM LED running lights removable for service but able to withstand the harsh life of being mounted to the pulpit of a 35ft racing sailboat. They will be an excellent choice for mast base connections and bilge pumps and engine room terminals where previously you had to use heat-shrink butt connectors for reliability.
