2000 Toyota Avalon third brake light

Ok I am flying blind here as all I have is memory of what it looks like. It is at the back window and there should be two screws that hold the cover on it. These screws may have covers over them to hide them. Then that will expose it and the bulbs should be there for the pickins. If you need to you can send me a pic and I will look it over but if you do send it from the back side inside the car ok. Hope this helps.
