1. Make sure headlamp is off and open hood. 2. Taurus model years 1990-1999: you must remove the whole headlamp to replace the bulb. Not a horrible task. Just annoying. 3. Facing the driver's side headlamp, and looking at the headlamp itself, at clock positions 8, 11 and 1 are the headlight housing screws. They all look the same. Using a 10mm socket wrench, remove these 3 screws and set them aside. 4. Just to the right of the "11 o'clock" housing screw is a bolt (same hexagonal 10mm sized top as the housing screws). This just needs a few turns to loosen it. 5. Gently pull the whole headlight forward. Now you can get at the bulb. 6. Disconnect the electrical connector from the bulb. Now the headlamp is free to work with. Remove the bulb, replace with a new bulb, make sure the bulb housing cylinder is in place and reconnect the electical. 7. Place headlamp back into position. Line up screw holes. Tighten the bolt. Replace housing screws and tighten. 8. Passenger side headlamp is mirror image of driver's side. Screws at 11, 1 and 4 o'clock positions. Bolt should be to the left of the "1 o'clock" housing screw.
