12 Volt Indicator Lights available in different colors and as either LEDs or incandescent. Often used in panels as circuit status indicators. LED indicator lights offer a lower current consumption and longer lifespan than incandescent lights, but are less tolerant of voltage fluctuations. Incandescent indicators are also polarity insensitive - meaning it doesn't matter which wire is positive and which is ground, Regardless of the type of indicator light, they usually have at least a 25,000 hour lifespan. Indicator lights come with either a wire pigtail for connection, or 1/4 inch push on tabs.
