This late-style wedge base bulb from Cycle Pro LLC features a specialized plastic locking system designed for modern Harley-Davidson lighting assemblies. This dual-filament version is commonly found in taillight housings and is also used for combined turn signal and running light functions on various models. The wedge design provides a secure vibration-resistant connection within the socket, which is critical for the harsh environment of a V-twin motorcycle. Whether used as a primary taillight or a front indicator, this bulb ensures consistent illumination and reliable performance. These bulbs are sold individually, making it easy to replace a single burnt-out unit in your lighting array.
