How to replace up rear brake lights on Aveo 2007, hatchback?

So, I am not sure if this thread was already made.
Car is Aveo hatchback 2007.
I want to replace brake lights on upper side of rear door. Its a set of 5 (I think) bulbs. I would like to put LEDs.
Already tried once, but I gave up. I was afraid of breaking something.
Anyone has a good how to tutorial?
tnx

To replace the CHMSL (center high mounted stop light) the directions are in the manual. Do you have yours? if not its page 283 here http://www.chevrolet.com/content/dam...veo_owners.pdf
