Replace The Headlight Bulbs on a Ford Fiesta ST
At some point, one of your headlights will go out. Depending on the car, it could be simple or extremely complex. With the Fiesta ST, all you need are two screwdrivers to do the job.
Locate the two screws and one plastic pop rivet.
Use a slotted screwdriver to remove the front screw, and a Phillips screwdriver to remove the pop rivet.
Use a slotted screwdriver to remove the rear screw.
Unplug the headlight from the car.
Pull up on the headlight to release it from the white plastic clip that is still holding it in the car.
Each bulb has its own cover. For the low beam, remove the large rubber cover.
Twist to remove the old bulb, and unplug it.
While not touching the glass of the bulb, install the new bulb and plug it in.
Replace the rubber cover and reinstall the headlight in the car by following the reverse of the procedure above.
When reinstalling the headlight, be careful not to scratch your paint!
