Summarized by Shop
A navigation-light monitor that lets you check your nav lights from the helm. It's a paired set — gauge plus relay box — with an LED for each light: if a bulb blows or a cable breaks, that LED goes out, so you can see at a glance which light has failed.
It works with traditional incandescent or LED navigation lights.
