DEKOR Lighting has designed a fast, simple and incredibly easy method to add lights to your existing deck without disrupting, disassembly, or removal of any existing rails or posts. DEKOR now offers wire covers in 3 colors: Brown, Black and White. The tools required: a hammer, a drill, a 3/8” drill bit and one Phillips driver bit. Whether you prefer a railing light or a post cap light, the installation process is very similar.
