Difficulty: Beginner · About 15 min · Ford Focus

Replace a Ford Focus side marker bulb or lamp assembly, seating the socket fully and checking that the light illuminates afterward.

Steps

1. Replace the bulb

   Turn the light off and rotate the marker socket out of the housing. Remove the old bulb, press in the correct replacement, and twist the socket back into place.

2. Remove the lamp assembly if needed

   If the housing is damaged, remove its retaining nuts from behind the panel and pull the assembly straight out without stressing the wiring.

3. Install and test the marker

   Seat the replacement housing and tighten its retainers evenly. Reinstall the bulb socket and switch on the parking lights to verify the marker works.

Check your vehicle’s repair manual for exact specifications and fit.
