Subsea RGB LED Indicator

The Subsea RGB LED Indicator offers over 16 million colors! It consists of an RGB LED built into the bulkhead penetrator form factor, which makes for easy installation in our Watertight Enclosures or other hardware.

At its core, it uses an LED with an internal driver very similar to a WS2812B LED, also commonly known as a NeoPixel LED, enabling fully customizable lighting control. It requires a microcontroller capable of sending WS2812B serial signals and is compatible with all major WS2812B software libraries, including Adafruit NeoPixel library, FastLED, and WLED.

The Indicator body is made of black anodized aluminum. A plastic diffuser cap spreads the light for an even glow. A 1000 meter depth rating and wide operating temperature range make it great for a variety of underwater environments.

Applications could include displaying error codes or system status information, a waterproof indicator light on an uncrewed surface vessel, or even an underwater light display with animation or scrolling text (we’ve dabbled in this ourselves).

They’re daisy-chainable!

Multiple indicators can be daisy-chained together by connecting the output of one unit to the input of another. This enables a single control signal to manage multiple lights, perfect for coordinated status displays or dynamic underwater lighting effects. Each indicator is fully addressable, so you can program them to create animated lighting and scrolling text effects.
