How to fix RX8 Tail Light

Hello. I drive a 2004, manual, 1.3L two rotor Mazda RX8. I have recently discovered that condensation is building up in my right tail light. There are no visible cracks. I took the tail light assembly off the car, but could not figure out how to take the assembly apart to clean out the condensation (it appeared to possibly be glued together). My question is this: Can you take the tail light assembly apart (i.E. Does it snap or screw apart, etc.), And if so how? And if it can not be taken apart, do I have to replace the entire assembly? Thank you.
