Bulbs

Ford Focus Bulb Sizes

2018 Ford Focus stores 24 bulb-chart rows across 22 lighting positions. Halogen low beam is H11. Halogen high beam is H1. LED headlight equipment is stored as its own configuration, not as an extra bulb in the halogen lamps.

Stored halogen, HID, Bi-LED, and LED rows are alternative equipment when the chart lists more than one. A vehicle uses one lighting system. Verify the lamps installed before ordering. A halogen bulb is not the replacement for an LED assembly, and an LED conversion is not shown as the OEM halogen bulb.

Replacement check

Read the number on the installed bulb or the housing. Confirm whether the headlights are halogen, HID, or an LED assembly. H11 and H11B are different. 9005 and 9006 are different. This page does not substitute a nearby designation to fill the product list.

Questions

What is the Ford Focus low-beam bulb?

2018 Ford Focus stores H11 for the halogen low beam. Choose the LED headlight configuration separately when the chart lists one. These are not installed together.

What is the Ford Focus high-beam bulb?

2018 stores H1 for the halogen high beam.

Does the 2018 Ford Focus chart include fog lights?

No fog-light bulb is stored for this year. This page does not add one.

What turn-signal bulb does the Ford Focus use?

Halogen-configuration turn signals in 2018 store 7440A, 7507, 3757A, 3157. An LED-headlight configuration can list LED instead of these bulbs.

What brake-light bulb does the Ford Focus use?

Halogen-configuration brake lights in 2018 store 3157R.

Does the Ford Focus have both halogen and LED headlights?

The chart stores halogen-headlight positions and LED-headlight positions as alternative equipment. A single truck uses one of those systems. Verify the lamps on the vehicle before ordering.

What does an LED record mean?

A stored part of LED means that configuration is recorded as an LED assembly. It is not a replaceable halogen bulb, and this page does not sell an LED conversion as the OEM bulb for that assembly.

How are HID bulbs handled?

D-series capsules such as D1S or D3S are HID. Exact catalog matches for those positions use HID products, not halogen bulbs.

Can I substitute a nearby bulb number?

No. H11 and H11B stay different. 9005 and 9006 stay different. This page matches the stored designation and does not swap in another bulb to fill the product list.

Does a catalog match guarantee the bulb fits?

A designation match means the product is filed under that bulb number and technology. It does not prove the lamp, socket, or vehicle configuration. Check the bulb in the housing before ordering.

How do I verify the replacement?

Read the number on the bulb or the housing, confirm whether the headlights are halogen, HID, or LED, and match that designation. Position names that say “with halogen headlights” or “with LED headlights” are separate configurations.

Does the Ford Focus bulb chart change by year?

Bulb rows are stored for 19 years, 2000–2018. This page shows 2018. Choose another year to see that chart. Years are not collapsed into one bulb list.

What does the chart store for back up reverse light bulb?

2018 stores 921 for Back Up Reverse Light Bulb.

What does the chart store for center high mount stop light bulb?

2018 stores LED for Center High Mount Stop Light Bulb.

What does the chart store for daytime running light bulb(hatchback, with halogen headlights)?

2018 stores H1 for Daytime Running Light Bulb(Hatchback, with halogen headlights) in the halogen-headlight configuration.

What does the chart store for daytime running light bulb(hatchback, with led headlights)?

2018 stores LED for Daytime Running Light Bulb(Hatchback, with LED headlights) in the LED-headlight configuration.
