I'm assuming you're referring to the brake light at the top of the liftgate. If all the other brake lights work then I'd start by replacing the bulb. If the other brake lights don't work either I'd start checking fuses.
I doubt it is LED. Very few (if any) cars had LED brake lights in 2005. I believe you access the bulb by popping off two plastic covers at either end which exposes some phillips screws. This releases the reflector and the bulb is a socket in the back.
Be careful with those two little red plastic covers on either side covering the screws. I've lost/broken two of them and the replacements cost about a hundred times their cost to manufacture ($6 from the dealer for a part that might cost 6¢ to make). Oh, and the hassle.
I'd just add to use a little rag over the pick (or flathead screwdriver) as Honda recommends, to reduce the risk of breaking the little tab, without which the two little triangular red plastic covers won't snap into place anymore and you'll probably lose them while driving. They are annoying and overpriced to replace, as I noted above, so best to avoid the hassle.
The video is helpful because the third brake lamp tends to burn out quite often. Lots of Pilots driving around not realizing (or not caring) they're out.

That is a good tip, I'm guilty of doing that in the past on occasion. Also if you have one that fits loose and you're afraid it might fall out, you can use a very small dab of rtv silicone as a holding agent. I use it on a holding point opposite where you would insert the pick. This way you can pry it open as you normally would and pull it apart.
