Subsea LED Indicator


This Subsea LED Indicator light comes in four colors and provides a high pressure on/off or status indicator light.



The Subsea LED Indicator is a simple LED light with high pressure capability! It comes in a penetrator form factor for easy installation on any of our Watertight Enclosures and it comes in four colors: white, blue, green, and red! It operates on 3-18V and each light draws up to 30mA when used at 18V. A built in resistor makes it easy to use without any additional parts.

The indicator light body is made of anodized aluminum. A plastic diffuser cap on the front creates a gentle glow and makes the light visible from any angle.

The Subsea LED Indicator can be used to provide status information about anything built into a watertight enclosure. Here are a few examples:

  • Use it as a power on/off indicator on the BlueROV2 or other device (especially when using aluminum tubes)
  • Install a few different colors on an underwater sensor enclosure to show status or errors
  • Use it as a waterproof indicator light on an unmanned surface vessel
  • Create an underwater light display!

It comes with two male header pins (0.1″) preinstalled to make it easy to connect to an Arduino or other electronic device.
