How to replace taillights in a 2001 toyota echo?

How do you replace the left side taillight for a 2001 Toyota Echo. I've looked on Google and there is only an eHow on it which didn't help at all. I need like specific names of things not just "then pry it loose with a screwdriver". Help is needed I have to register my car soon.
