I decided to replace all the light bulbs that weren't on, the bulbs in the Focus are easy to change.
Replacing the Ford Focus 3 headlights is extremely simple, the headlight is held on by 2 bolts:
Headlight fixture.
You can unscrew a lot of things: an asterisk, a hexagon, well, or a large flat screwdriver.
Same bolt and sprocket.
Actually, after removing the headlight, it is enough to remove the necessary protective rubber band and replace the light bulb.
The reverse side of the headlight.
For those who, like me, have to disconnect the headlight (you don’t need to do this to change the light bulb), I advise you to look at this (not entirely intuitive):
Disconnecting the connector.
Everything is put in the reverse order.
