Not sure about disassembly, I just popped the covers off to see what type of lamp base and then counted the fixtures. Had a few incandescents that were spotlight type reading lamps that I found LEDs for at a local truck stop store. This Spring marks the start of our third camping season since our LED conversion, they are brighter, run cooler, and use a fraction of the power of the incandescents they replaced. An absolute must mod for those who tend (or prefer) to camp off the power grid. It felt like we nearly doubled our available stored 12Vdc power after the conversion was performed.
