It provides a secure electrical connection between the vehicle's wiring and the lamp using a female flag terminal on the lamp side and two male bullet terminals on the power side. The pigtail is built with 18-gauge GPT wire and measures about 7‑3/4 inches overall, making it suitable for repairing damaged or corroded wiring. It’s commonly used on heavy-duty trucks and trailers to restore reliable marker light function.
