Brake light replacement

I have a 1999 Ranger that needs a brake light replaced for the first time.  I took out the two screws, but can't get the lens off.  It's seems like it's still attached.  I don't want to pull to hard lest I break the lens.  Does it just pop off, or am I missing something?  Thanks.

There are four screws you need to remove. two on the outside and two on the inside. just put your tailgate down to get to the inside two. mine came out easily after removing the screws. hope this helps

Great...I will try that when I get home this evening.  Thanks again.
