The LED Dimmer Control is engineered with a rugged waterproof design for your harsh marine applications. This dimmer control not only will dim your Blue Water LED lights but also has an off position so you don’t need to add an On/Off Switch to your lighting circuit. This easy-to-install dimmer has one connection for your power and one more for your LEDs. The connections are easy to work with, sturdy, and include the female connectors to hook it up. The LED Dimmer Control works with all Blue Water LED deck or compartment lighting systems.
