I would like to fit soffit down lighters at the front of my house. Only 4 of them, but Ive had a quote for £320. I thought this was a bit over the top so would like to tackle it myself. I currently have a porch light in the soffit above my front door. Can I just take the wiring from that, & then is it just a case of linking the 4 lights together? i.e. the main wiring to the first light, then each one linked thereafter? Thanks
