Montana provided convenience motion detector lights in the entry and on the first step on our 2020 fifth wheel. That gave us the idea to install a $13 usb rechargeable motion detector light with velcro in the bathroom. The light has 3 colors, which we set to the sleep friendly color. Avoids turning on the bright bathroom light, especially at night. It comes with 2 so we installed the other one in the home bathroom.
