1) Open your Hood
2) Inspect the bumper edge at the top which would normally be covered by the Hood
and you'll notice there are 4 10mm bolts that need to be removed.
3) look behind the Toyota Elblem and there is a plastic brace about 2 inches long that needs to be removed with a simple upward push with a flathead screwdriver.
4)Lay on your back in front of the car and look right under the bottom of the bumper and you'll see a series of 8-10 10mm bolts that need to be removed.
5) Inspect the wheel well on both sides and you'll find there are 2 10mm screws, one in each wheel well.
6) Reach your hand behind the bumpers through the wheel well to turn the back of the corner lights off counterclockwise.
Hope that helps
