Lexus Repair: Lexus RX-300 Tail Light, lexus rx 300, rear fender

Question
I'm trying to replace the tail light on the rear fender portion of a 2000 RX-300.  It is not one of the lights that are on the hatch.  

When you open the hatch, there are two vertically aligned screws you can remove that hold the light assembly in place, but the assembly still will not totally detach.  

I'd appreciate any advice/directions you can provide.  Thanks.
Ray

Hello Ray,
 I'm sorry for the delay. I couldn't see your question until today. Hopefully it's not too late. I belive there are two 10 MM nut inside the vehicle. Feel free to give me a call if you need additional help 214-221-3135.
