How to Remove a Ford Focus Headlight Relay
Headlight relays are circuits that help provide power to your headlight system. If your headlights are not working, you may have a faulty relay. Removing a relay is simple once you locate it. The Ford Focus has several headlight relays; each powers a specific headlight beam.

Relay 17 powers your passenger side low-beam; relay 27 powers your passenger side high-beam. Remove the plastic fuse box cover and use the numbered diagram to locate the relay.
