Open the hood. Remove the black plastic grill assssembly ( Laying horizontal between the radiator and front bumper). There will be a couple of plastic screws (or some other fastening system) for this part remove and set aside. There is another black plastic grill assembly standing vertical. Remove similar fastening devices and set aside. IF DURING THIS ENTIRE PROCESS there is ANY part that does not come off freely after removing a fastening device (plastic screw, metal screws, hex bolts, bolts) LOOK FOR A PLASTIC CLIP - unclip that as a final step in each of these processes. To continue, Each headlight is attached by three hex or phillips screws.- Remove them and set asside. There is a major clip attaching the headlight at the top. Unattach this and gently remove the entire light housing. The housing will be the unit containing all parts high beam, low beams, side lights, and blinkers. It is a nice tidy unit. To continue, look for a black plastic removable panel on the back allowing access to the back of the bulbs. Remove the 5 screws and set asside. You now have access to the bulbs. The bulbs are attached by a solid plastic clip. Grab the back of the plastic bulb housing and turn about a half of an inch to remove the bulb. Unattach the clip from the wirering harness and you will have the bulb removed. CAREFULLY remove the new bulb making sure not to touch the glass portion of the bulb with hands directly. Skin oils or other debris is not recommended to get on the bulb. Deliberately refasten the bulb wiring harness and replace to the back of the reflection housing. Reassemble all devices. Rinse wash repeat for the other side :)

This seems complex for the task at hand and it is. But from the perspective of repairing a front end after a minor collision is is wonderful. Enjoy...
