Additional Notes

The Ford Ranger backup light specifications cover model years 1983 through 2023, with seven distinct bulb sizes appearing across that span: 1156, 2356, 2456, 2355, 3156, 3157, and 7440.
The 7440 is a single-filament T20 wedge bulb rated at 12V and 21W. It is the most frequently specified backup light bulb in the Ford Ranger lineup, appearing across the 2019-2023 model years under standard tail assembly configurations.
The 3157 is a dual-filament T25 wedge bulb rated at 12V with a 27W/7W output split between its two filaments. On the Ford Ranger, it is specified only for vehicles equipped with halogen capsule headlamps (2019 and 2020) and for the Type 1 lamp configuration in 2023.
The 2023 Ford Ranger requires two different bulb sizes depending on lamp type: the 7440 for the Type 2 (standard tail assembly) and the 3157 for the Type 1 lamp. Selecting the wrong bulb for the installed lamp type will result in an incorrect fitment.
The 3156 is a single-filament T25 wedge bulb rated at 12V and 27W. It shares the same T25 wedge housing as the 3157 but has only one filament, making the two bulbs physically similar yet electrically distinct and not interchangeable in dual-filament sockets.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W. It was specified for the Ranger across the 1983-1988 model years and uses a bayonet mount rather than a wedge base, making it incompatible with wedge-style sockets.
The 2355 and 2356 both use a BAY15d bayonet base and are dual-filament bulbs rated at 12V. The BAY15d base has two offset pins, which physically prevents installation in a BA15s single-filament socket, and vice versa.
The 2456 is classified as a festoon bulb intended for specialty applications, rated at 12V. Its festoon form factor differs structurally from both wedge and bayonet-base bulbs, and it is not interchangeable with those types.
The 2355 was specified for the 2008-2011 Ranger, while the 2356 appeared across several earlier years. Although both share the BAY15d bayonet base, they carry different electrical ratings and are not confirmed interchangeable by these specifications.
For the 2019 and 2020 Ranger, two backup light bulb sizes are listed simultaneously, with fitment determined by whether the vehicle has halogen capsule headlamps or a standard tail assembly. Both conditions must be verified before selecting a replacement bulb.
