Additional Notes

The 881 is the sole bulb type listed across all model years in these specifications, covering the Harley-Davidson FLHTCUTG Tri Glide Ultra front fog light for 2011-2013.
The 881 is a single-filament halogen bulb, meaning it serves one lighting function only and cannot replicate the behavior of a dual-filament bulb in applications that require two separate brightness levels.
It operates on a 12-volt electrical system at 27 watts, which places it in the lower wattage range typical of fog lighting applications where broad, low-mounted illumination is prioritized over long-range projection.
The 881 uses a PGJ13 base, a proprietary locating base design that physically prevents it from being seated in sockets intended for other base types, making cross-installation with incompatible bulbs unlikely without modification.
The 881 conforms to ANSI standards as recognized in the United States and Canada, indicating that its electrical and photometric output meets a defined industry specification rather than a manufacturer-specific rating.
Because the PGJ13 base is specific to the 880 bulb family, substitutions from outside that family, such as H11 or H8 types, are not physically compatible without an adapter, even if wattage ratings are similar.
