It has factory-molded plugs with a star ring and .180-inch male terminals that snap directly into the lamp body, creating a weather-tight seal to prevent moisture and corrosion. You typically replace this pigtail when the original connector is damaged, corroded, or broken, causing intermittent light operation or total failure. It's a direct service replacement for Grote lamp models 5206, 5202, and 5306.
