How do you change the brake light bulb in a 1997 Toyota Corolla?

I tried from inside the trunk by taking out the screw, then unscrewed the outside screws, but here are two plugs that won%26#039;t allow me to take out the brake light to change the bulb. Any suggestions?|||You more than likely have to pinch the plastic bulb sockets before you can turn them. Think of a child-proof medicine bottle cap.|||take a screw driver, pop of the plastic plate and take the old light bulb out and put a new one in:)
