How to Replace a 1998 Ford Taurus Head Light Bulb. The 1998 Taurus is a sedan designed and manufactured by Ford Motor Company. The Taurus is equipped with headlights that use light bulbs to ensure visibility during nighttime driving or tough weather conditions, such as rain or snow. Over time, the headlight bulbs may burn out and need to be replaced. It's important to learn the proper way to replace the bulbs to ensure safe driving and avoid a traffic violation.
Turn the headlight switch to "Off." Place the Ford Taurus in "Park" and turn the engine off. Engage the emergency brake to ensure the vehicle does not move while performing maintenance. Open the hood of the Taurus. Locate the headlight with the burned-out bulb.
Unhook the clip securing the headlight bulb and electrical connector. Remove the electrical connector from the back of the bulb.
Remove the bulb's retaining ring by rotating the ring counterclockwise to unlock it from the bulb socket. Slide the ring off. Keep the socket in a safe place, as it will be needed for the replacement bulb.
Pull the burned-out bulb out of the headlight unit by pulling it straight out towards you. Do not turn the bulb. Discard the bulb.
Insert the glass end of the replacement bulb into the headlight unit. Make sure the flat side of the plastic base is facing up. Align the grooves on the plastic base with the tabs located on the headlight unit. Push the bulb into the headlight unit until the base is positioned at the rear of the headlight unit.
Slide the retaining ring over the plastic base. Secure the ring by rotating it clockwise until it stops. Plug the electrical connector back into the rear of the plastic base. The connector will snap into place, signaling that the connection is secure. Push the securing clip back into place. Repeat these steps, if needed, for the opposite bulb.
