So I have aquired 1 light of a traffic light that I salvaged from a local dump. I want to try and connect the light to use it like a lamp, however I am a little worried by it as the connector only has live and netural wires.
Basically I want to know if it is possible to earth the system or is it safe without earthing? I read into double insolation but cannot tell exactly how it works.
Sorry if this is very basic or been answered somewhere else, I wasn't exactly sure of how to find an answer.
