It has a molded Super 21 plug on one end that connects directly to the back of compatible incandescent lamps, and a stripped wire on the other end for splicing or crimping into your truck's wiring harness. You'd replace this pigtail when the original plug becomes corroded, the terminals lose tension, or the wire is damaged, causing intermittent or failed lighting. It uses 16-gauge GPT wire and tin-plated brass terminals for reliable conductivity in high-vibration, exposed environments.
