2015 Ford F-250 Super Duty Bulb Sizes and Replacement Guide

Quick Reference: 2015 Ford F-250 Super Duty Bulb Sizes

The 2015 Ford F-250 Super Duty, a workhorse known for its rugged capabilities, came with a variety of lighting configurations depending on the trim level. M ost models utilized traditional halogen bulbs, but some higher trims or optional packages might have featured factory HID (High-Intensity Discharge) projector headlights. It's crucial to verify your specific setup before purchasing replacement bulbs.

For the low and high beams, the most common size is the H13 halogen bulb. However, if your F-250 has the optional projector-style headlights, these will often use a D-series HID bulb (like D3S), which is not interchangeable with halogen. Fog lights typically use a 9145 (also known as H10) halogen bulb. Daytime Running Lights (DRLs) and front turn signals often share the same bulb, a 3157 or 4157NAK (amber), and can be incandescent or LED depending on the trim and options. Rear turn signals, brake lights, and tail lights commonly use a 3157 incandescent bulb. Reverse lights can be either a 3157 or a smaller 921 bulb. For smaller illumination needs, such as license plate lights and front side markers, you'll generally find 168/194 bulbs. Interior lighting like the dome and map lights often use a 578 festoon bulb for the dome and 194 bulbs for the maps.

CANBUS Errors: Modern vehicles like the F-250 utilize a CANBUS (Controller Area Network Bus) system to monitor various electrical components, including lighting. Halogen bulbs draw a specific amount of power. When you replace them with lower-wattage LEDs, the CANBUS system might detect the reduced power draw as a
