Actually, they were offered for some time in the U.S. before being ousted from the options list. I purchased my new 96 RAV4 with the factory fog lights - the Hella 500 fog. They are drilled into the top surface of the front bumper.
You can purchase Hella 500's anywhere, but I highly recommend stronger ones. Almost any light can be drilled into the RAV4's bumper, and I recently replaced the Hellas with PIAA 520s in the same drill location.
As for a picture, it's coming soon. Good luck on your lights.
