BULB - 12V 55W H3 (JLG JL916564)

A bulb that fails can leave a vehicle without critical exterior lighting during operation. This aftermarket replacement references JLG as the OE maker and carries the catalog number JL916564. The part is a 12V 55W H3 bulb, a type commonly used in work-vehicle headlamps and auxiliary lamps. Its plain mechanical function is to produce light when energized by the electrical system. A generic failure consequence is that a burned-out bulb reduces visibility and may result in an unsafe operating condition. The vendor lists the specification as 12V.
