Taking this into account, what is the type of switch you would prefer to operate the lights above or behind your bathroom mirror?
Wired into the main lighting. (so the mirror light operates with the main bathroom light)Pull cord operated. (A pull cord on the mirror unit operates the light function)Sensor Operated. (A sensor housed in the mirror, detects your presence and operates the bathroom mirror light)
Always usa Fully Qualified Electrician Regardless of how you choose to have your bathroom mirror lights operate. It is important that you ensure that the mirror is installed by a fully qualified electrician and pay attention to the type of mirror you are buying. You have to make sure that the IP rating matches the zone in the bathroom where you intend to install the bathroom mirror.
