tailight cover on 2008 Class C Four Winds Siesta

I just got a load of sealed LED tail lights for the local mechanic. 9-30 volts operation and the only thing to maintain are the 3 8" pigtails sticking out of the tail light. No grit, no water means zero maintenance. These lights fire to full brilliance (10 volts) when 2000c bulbs fall flat on their face.
