Questions

What is the Ford Focus low-beam bulb?

2003 Ford Focus stores D2S 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?

2003 stores H7 for the halogen high beam.

What fog light bulb does the Ford Focus use?

2003 stores 899 for fog lights.

What turn-signal bulb does the Ford Focus use?

Halogen-configuration turn signals in 2003 store 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 2003 store 3157R.

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.

Bulb rows are stored for 19 years, 2000–2018. This page shows 2003. Choose another year to see that chart. Years are not collapsed into one bulb list.
