Hi all. 2006 LC. I've finally started ripping apart my rear cargo area (3rd row seats removed long ago) as I clearly have a leak somewhere. Sitting in the back while my wife ran through the carwash revealed the trouble spot. First up is the upper rear brake/tail light on the upper hatch. I'm ready to remove it, clean it, and RTV the heck out of it. I pulled the rubber plus on the inside of the hatch to access the brake/tail light mounts. I consider myself reasonably handy, but I cannot figure out how the remove that light. The mounts almost look like a pop rivet. I know they aren't, but I'm not sure how or with what tool to remove it. Any hints/advice? TIA!
