Want everybody to know you have a cool USV??? Add the NavLight to be sure to catch their eye!

The NavLight is a high-brightness LED light designed to make USVs, buoys, and other marine craft visible from a long distance. It’s extremely compact with a G4 bulb in an M14 penetrator form factor.

The light runs on 5-12 V, draws up to 2.5 W of power, and outputs approximately 180 lumens of light. Internal circuitry allows it to be controlled by an input signal from a microcontroller like an Arduino or the Navigator Flight Controller so you can turn the light on and off or create flashing signals. If you don’t have a control device, simply connect the input signal to power to turn the light on.

The Navigation Light can also be used in subsea applications and has a 1,000 meter depth rating when installed on an end cap or when coupled with a WetLink Penetrator installed on the end of the cable. That allows you to mount it anywhere on your vehicle—it’s not restricted to use on an enclosure end cap.

The light comes with a 60 cm cable length and O-ring and nut for installation. Check out the usage guide for more details.
