There are four nuts that hold the bezel in place. You'll have to pull back the lining material and you'll see them. Make sure you take out all four. There is one that is kinda hard to see as it's close to the top and hidden by the metal of the trunk lip. I believe I used a 10mm socket.
Once you remove the four nuts, the bezel can come out but it's TIGHT. What I did was gently tap on the bolts (from where you took off the nuts) and it should come out. Pull it straight back or else it's really difficult to get out. The right side has the trunk keyhole so make sure that's lined up when replacing it. Once it's out, changing the bulbs is a snap.
I would recommend getting the bulbs from the dealer as the ones from AutoZone, etc., aren't right. I had the wrong parking light (peanut) bulbs and it caused the dash light to come on. ONce I put the right ones in, it solved the problem. Also, I have a 97 which doesn't use the double-filament bulbs for the brake but AutoZone called for it.
In fact, the reverse, stop, and turnsignal bulb were all the same (single filament).
Let me know if this helps.
