I have removed my strip lights from the garage to find 3 main wires go into one, then 2 main wires out one to each other seperate strip light. Can anyone tell me why 3 main wires go to first light? I am repalcing only 2 lights, do i need to run all wires into first light then take one lot out for second light?
When i say main wire i mean one grey wire with 3 wires within it, red, black and earth, therefore in total i have 3 red, 3 black and 3 earth. Hope this makes sense!!
