Repairing the a taillight on a Ford Focus requires disconnecting the battery and replacing the housing from the vehicle. A cracked or damaged taillight housing does not allow the light from the bulb to shine properly. If the unit is not promptly replaced, the driver of the vehicle may be fined by local law enforcement.
The taillight's main function is to warn other drivers of the vehicle's presence. When the housing is cracked or damaged, water can enter, causing the bulbs to fail and wiring to shorten. To avoid any fines or accidents, a damaged taillight needs to be replaced. The following instructions explain how to replace a damaged taillight on a Ford Focus.
- Disconnect the battery
- Locate the taillight
- Remove the bulbs
- Loosen the taillight bolts
- Inspect the replacement housing
- Install new bulbs
Locate the battery inside the vehicle's engine compartment, and disconnect it to avoid any accidental shock.
The taillight mounting location is found inside the trunk. Open the trunk and pull back the plastic panels.
Twist the bulb out of the housing.
With the bulb removed, loosen the mounting bolts found behind the taillights. Then push the housing out.
