You must remove the entire light assembly as follows: Lower the tail gate and remove the two small screws that screw into the side of the assembly. Next remove the two screws on the outside of the assembly that are accessible through long holes on the outside of the assembly. Pull the assembly back to expose the rear where the lights are located.
replace it
you DO NOT disassemble the lens cover!!!! Open the hatch, and you will see small access panels directly behind the taillights that open. Just open the panel and take the bulb out.
You have to go inside the trunk and remove the circular plastic covers from behind the lights. Then you have to unscrew the entire light and you can access the bulbs to replace them.
My 2007 Mazda 3 has very detailed instructions on how to do so...check your owner's manual to see if its the same situation on the 2005 RX8. See sources and related links below for more information on bulbs.

3rd brake light or rear brake lights?
Lift the car on a vehicle jack, remove the tire, remove the brake shoe/caliper and remove the old brake pads. Put in the new brake pads, replace the brake shoe/caliper, replace the tire and lower the car to the ground.
You have a warped brake rotor(s). Resurface or replace the effected brake rotors.
Take your truck to mechanic man to do it for you
That is because it is not a chain. Mazda uses a timing belt which must be replace at 105,000 miles if not before.
