Bathroom Deoderizer Control - That box you see on the wall in public washrooms. HOME

This is the type that has a little DC motor fan positioned above a small container containing a deoderant liquid or jelly, and runs off a D cell. The photocell turns off the fan when it gets dark. The LED flashes if the battery is good.
