Additional Notes

The 881 bulb is the sole front fog light bulb type listed across all model years of the Harley-Davidson FLHRC Road King Classic covered in these specifications, spanning 2007-2013.
The 881 is a single-filament halogen bulb, meaning it serves one lighting function only and does not share its filament between multiple roles such as fog and running light duties.
It operates on a 12-volt electrical system at 27 watts, placing it in the lower wattage range typical of auxiliary lighting applications rather than primary headlight use.
The 881 uses a PGJ13 base, which is a specific locating and retention design. Bulbs with different base types are not physically interchangeable with this socket, regardless of similar wattage or voltage ratings.
The 881 carries ANSI standardization recognized in both the United States and Canada, indicating the bulb conforms to a defined set of performance and dimensional criteria under North American standards bodies.
Because the same bulb size is specified across all seven listed model years without variation, replacement bulbs sourced for any year within the 2007-2013 range share the same fitment requirements.
