Hi, Need a steer please. Just installing a built in shower and want to ideally put some led low voltage lights in the shower ceiling. This is zone 1. What I want to do is leave the main bathroom lighting alone as that’s not zone 1 or zone 2 and it works fine via the pull switch. The shower runs from a pump and operated via a pull switch and what I would like to do is connect a transformer in parallel and run either a low voltage light in the shower ceiling or install some led lights like a "meteor" spray. Objective is to only have the light come on in the shower when someone actually wants a shower. Is this possible please and is there such thing as some sort of kit that can be used eg like the standard low voltage lighting transformer for a pair or LED lights. Thanks.
