Blue Sea Systems 8172 Green LED Indicator Light, 12/24V DC, for Traditional Metal Circuit Breaker Panels

The Blue Sea Systems 8172 is a green LED indicator light built for marine and RV DC electrical systems, giving an instant visual signal of power status, system activity, or alarm conditions on a switch panel. It operates on both 12V and 24V DC systems, drawing a low nominal current of 15 mA at 12V (19 mW), so it stays visible without placing meaningful load on the battery. The LED uses a resistor circuit and is wired with 26 AWG lead wire for straightforward panel connections.

Installation is a simple push-in design that mounts into an 11/64 inch (4.36 mm) hole and works in panel material of any thickness, so it is not limited to a single panel gauge. The 8172 directly replaces the LEDs used in Blue Sea Systems Traditional Metal circuit breaker panels, making it the correct choice when an indicator light on one of these panels needs to be swapped out or added. Whether used as a general power indicator or wired into an alarm circuit, it delivers dependable, low-maintenance signaling for the life of the panel.

Frequently Asked Questions

What color is the Blue Sea Systems 8172 indicator light? The 8172 is a green LED indicator light, part of the Blue Sea Systems lineup that also includes amber and red versions in the same style.

What voltage does the 8172 LED run on? It operates on both 12 volt and 24 volt DC systems, making the Blue Sea Systems 8172 suitable for a range of marine and RV electrical setups without needing a different part for each voltage.

How much current does the 8172 draw? At 12 volts, the 8172 draws a nominal 15 mA and consumes about 19 mW of power, a low enough draw that it will not meaningfully affect battery life even when left on continuously.

What size hole is needed to install the Blue Sea Systems 8172? The 8172 mounts in an 11/64 inch (4.36 mm) hole using a simple push-in design, and it fits panels of any thickness.

Does the 8172 require any tools to install? No, the Blue Sea Systems 8172 uses a push-in installation that snaps into the mounting hole without special tools.

What panels is the 8172 designed to fit? It is designed to directly replace the LEDs used in Blue Sea Systems Traditional Metal circuit breaker panels.

What wire gauge is used on the 8172? The Blue Sea Systems 8172 is wired with 26 AWG leads.

What type of circuit does the 8172 use? It uses a resistor circuit, the same type used across the Blue Sea Systems 8033, 8171, and 8172 indicator LEDs.

Can the 8172 be used for alarms as well as power indication? Yes, the 8172 is useful as both a general power indicator and as an alarm light, since it is simply a wired LED that lights when its circuit is energized.

How much does the Blue Sea Systems 8172 weigh? The 8172 weighs 0.03 pounds.

Is the 8172 a genuine Blue Sea Systems part? Yes, part number 8172 is the manufacturer's own green LED indicator, not a generic substitute, so it matches the fit and finish of the original panel LEDs it replaces.

What is different between the 8171 and 8172 indicator lights? The 8171 is the red version and the 8172 is the green version; both share the same 12/24V DC operation, resistor circuit, and 11/64 inch push-in mounting.
