I am looking to install 4" LED recessed lighting in my vinyl soffits. However under the vinyl is the old wood soffit. I do not want to cut through these wood soffits, but this will leave me with a clearance issue to maybe fit the LED recessed lighting without it's built on metal junction box. Can I cut off the junction box and splice directly to the LED with Romex, and run the 14/2 Romex inside the vinyl soffit between the vinyl and the old wood soffit from light to light?
