The Ford F-250 Super Duty brake light utilizes 3157, 2458, and 4157 bulb sizes depending on the specific version of the component required for the vehicle. Available information covers the span of time starting from 1999 through 2023 for the listed automotive lighting components.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford F-250 Super Duty uses the 3157 bulb for the brake light position across the majority of its model years, spanning 1999-2023, with the sole exception of the 2006 model year, which uses the 4157 instead.
Both the 3157 and 4157 are ANSI-standard dual-filament wedge bulbs in the T25 form factor, rated at 12V with a 27W high filament and a 7W low filament. The dual-filament design allows a single bulb to serve both brake and running light functions.
Although the 3157 and 4157 share identical voltage and wattage ratings, they are distinct ANSI part numbers and are not confirmed as interchangeable by these specifications. The 2006 Ford F-250 Super Duty is the only model year in this range specified to use the 4157.
For the 2017-2020 model years, the brake light specification of 3157 carries a "With Halogen Capsule Headlamps" condition, indicating that this fitment applies specifically to trucks equipped with that headlamp configuration.
The center high mount stop light on the Ford F-250 Super Duty transitioned from the 922 bulb to the 912 bulb between the 2010 and 2011 model years, and the 912 specification has remained in place through 2023.
The 922 is a T15 wedge bulb rated at 12V and 16W, while the 912 is also a T15 wedge bulb but rated at 12V and 12W. The 912 is described as a variant of the 921 bulb type. The lower wattage of the 912 relative to the 922 means the two are not interchangeable without accounting for the difference in output.
The 2019-2020 center high mount stop light entries also carry the "With Halogen Capsule Headlamps" condition, consistent with the same conditional fitment noted for the brake light position in those years.
All four bulb types listed across these specifications, the 3157, 4157, 912, and 922, conform to ANSI standards applicable in both the United States and Canada.
