This 2017 Ford Focus bulb size guide is organized by lighting position so you can quickly verify the correct replacement for each exterior and interior lamp. Because trim level, body style, and lighting package can change the fitment, the bulb chart on this page helps you match the right bulb to the exact location on your Focus before you buy.
Use this page as a reference for common 2017 Ford Focus bulb sizes for the sedan and hatchback, including headlights, turn signals, brake lights, reverse lights, license plate lights, dome lights, and map lights. It is especially useful when you want to compare halogen and HID-equipped models, since the bulb type can differ by front-end setup and market.
For the best fit, always confirm whether your 2017 Ford Focus has halogen headlights, HID headlights, or a lighting package that changes the bulb type. Some positions use LED modules, while others use replaceable bulbs, and aftermarket LED conversions may require a different base, polarity check, or additional hardware to work correctly. Before ordering, inspect the bulb already installed in your vehicle and compare it with the chart, since Ford used different sizes for sedan and hatchback versions and for certain front, rear, and daytime running light applications.
The low beam headlight bulb is H11 on the 2017 Ford Focus when equipped with halogen headlights. HID-equipped models use D3S for the headlight bulb listing shown on this page.
The high beam bulb size listed for the 2017 Ford Focus is H1. This applies to the fitment shown in the chart and should be checked against your specific trim and headlight package.
The front turn signal bulb for the 2017 Ford Focus is 7440A for the standard listing. Hatchback models with HID headlights use 7507 for the front turn signal bulb.
For the 2017 Ford Focus sedan, the rear turn signal bulb is 3157. Hatchback models use a different rear turn signal bulb size, so body style matters.
The 2017 Ford Focus hatchback uses 3757A for the rear turn signal bulb. This is different from the sedan, so it is important to confirm the body style before ordering.
The back up reverse light bulb size listed for the 2017 Ford Focus is 921.
Both the brake light bulb and the tail light bulb are listed as 3157R for the 2017 Ford Focus.
The license plate light bulb is LED on the 2017 Ford Focus, so the page lists it as an LED application rather than a standard replaceable bulb size.
Yes. Hatchback models with halogen headlights use 168 or 917 for the parking light bulb, while other parking light listings include 194 and 7441. Hatchback models with HID headlights use LED parking light bulbs.
The daytime running light bulb is H1 for the sedan listing, while hatchback models with HID headlights use LED daytime running lights. This is one of the clearest examples of trim and package differences on the 2017 Ford Focus.
The dome light bulb and map light bulb are both listed as LED on this 2017 Ford Focus bulb chart.
Checking the installed bulb helps confirm the exact fitment for your specific 2017 Ford Focus, especially if the car has been modified, has a different market specification, or uses a trim-level lighting package that changes the bulb type.
