It's my understanding that there is no direct replacement for this Model. I used this lens Peterson 375-15 Replacement Lenses - Replacement Lenses - in white and secured them with a dab of hot glue in each corner. They have been in service for about six months now and look great. The hot glue keeps them in place and allows the lens to be removed without much bother if I need to replace a bulb.
Thank You.... I recently bought the 1892 21RB Model same as yours. Couple of questions u might be able to help me with. 2 light switches when u enter the camper. 1 works outside light but what does the other work? Also switch in front of sink, cant figure out what that works either? THANKS
Mine has a single switch inside the front door that operates the exterior light - no second switch. Mine does not have a switch in front of the sink but I guess that it operates the electric 12v water pump? My pump switch is in the left rear of the trailer below the double closet and above the access door to the 120v Circuit Breaker Box. I suggest that you remove the kitchen drawers and see if you can trace the wires to their individual component. If you go to my Photo Album I have posted interior pics which show how it's configured. It might be slightly different than yours.
