Pictures of Parts Fog Lights
These pictures are just my experience of putting Fog Lights on my 2007 Camry LE.  I used Toyota Parts from Dealer and they sure help the looks of the car.  I have yet to hook up the electric to the lights as I am not sure to go with PIAA Xtreme White or with HID.

Housing in Bumper Assembly, Fog Light ears on one side just slide into the slots on the angle piece

Another view of slots without Fog Light Cover in place

Ears on light slide into slots, Fog Light Cover not in place so we can see how the light mounts

This is what I call the stub that the other side of the Fog Light Fastens to with a screw, I ordered mine from Toyota as these things can break easy with to big screw or the wrong thread, ect

Another View of the Stub that the screw fastens to, note Fog Light cover not installed to show how I mounted my lights
