Ford F-600 Super Duty Headlight Bulb Size

Additional Notes

• The 9008 bulb is the sole bulb type specified for the Ford F-600 Super Duty across both the 2021-2022 model years, covering both the high beam and low beam headlight positions.
• The 9008 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 65W for high beam output and one rated at 55W for low beam output. This design allows it to serve both lighting functions within one housing.
• The 9008 operates on a 12-volt electrical system, which is standard for passenger and commercial vehicle applications in this class.
• The bulb uses a P26t base, a specific bayonet-style socket type that determines physical fitment into the headlight housing. Bulbs with a different base type are not interchangeable with this socket, regardless of wattage or voltage ratings.
• The 9008 designation follows ANSI standards recognized in both the United States and Canada, indicating the bulb meets a defined set of performance and dimensional requirements established by the American National Standards Institute.
• The 9008 is also commonly cross-referenced as H13, and these designations refer to the same bulb type. Fitment compatibility depends on confirming the base type and filament configuration match the vehicle's headlight assembly.
