There are two 10 millimeter bolts that must be removed. Place these in your pocket or a convenient place so they will not be mispalced or lost. Also you need to pull upwards and remove an aluminun locking tab(coated in black plastic). After this is done carefully slide assembly foward. Press down on the wiring harness clip to remove it from the headlight bulb assembly, Turn the locking ring on the bulb to the right and remove so you can remove the bulb. Twist bulb out. When replacing new bulb do not touch the glass portion of the bulb. If you do so clean off with alcohol. Oil from your fingers left on the bulb will cause the bulb to overheat and fail prematurely. Replace bulb and secure with locking ring. You may also want to change the yellow parking/signal light bulbs at the same time. Clip wiring harness back on and slide headlightassembly back into place. Slide aluminum locking tab back into place. Now hand thread 10mm bolts back into place, Then tighten, do not over tighten. Now do the other side. First time might take you about 10 minutes per side. After that you could do it in a couple of minutes. Info on performing this maintenence can be foud in the owners guide or by downloading the guide from the following link http://www.motorcraftservice.com/pubs/content/~WO1SAB/~MUS~LEN/40/01sabog3e.pdf

Hope this info helped.
