SnugTop Canopy Leak

After having my canopy on the truck for 3 years with no problems, I got into the back this morning to discovered a puddle on bed mat. It looks like it's comeing in around the 3rd brake light on the back of the canopy. Has anyone else ran into this issue with their SnugTop, and what did you end up doing to fix it?

 

Check to make sure the 3rd brake light is still snug. I had a snugtop for about a year and I seem to remember one side of the 3rd brake light getting a bit loose and starting to barely leak. I sold it before addressing the potential problem though.
