Thanks for the additional info. I saw some 3rd brake lights on ebay for under $40 shipped with a 30-day warranty, so I think I will try one of those. And I think I'll pop out the taillight assembly tonight and see if I can get it to work off the car, where I can see it better and maybe even repair it. I'll report back!
