The vendor that supplied the recessed puck lights seemed to have shipped an extra one we didn't order so I ended up installing it in the shower. It use is an improvement and you can see what you are doing in there now. This photo also shows a soap dispenser we added.
An interesting note on the light in the shower. When I cut the hole for the light and was fishing the wiring across to the exsting light, I discovered that when they installed the curtain track, they used 1 1/4" long screws with a really sharp point. Not a problem in itself, but for some reason there is a LOT (and I mean a LOT) of 120 volt and low voltage wiring immediately above the curtain track. This meant that over time, movement from towing the trailer all over the place could possibly damage the wiring leading to a fire. I'm pretty disgusted to find out this sort of thing. There's a lot of shoddy hidden work that I've come across. I ended up putting in shorter screws and small wood backing blocks. I had to reach in through the four inch hole up to my elbow to do some of them....not fun . I found one 120 volt receptacle that was improperly wired and could have overheated. I'm not impressed. I'm told by people in the 'biz that's this is pretty typical of how RVs are put together.
