The cost for adding store-bought lighting fixtures to your layout can be pretty expensive. With that being the case I'm including this link to my website that shows you a step-by-step tutorial of how to construct economical light poles. Cost? In 2006, parts for a single-light pole came to ~$1.50 and a double-light pole less than $3.00. The link includes a list of tools and materials you'll need to complete the light poles, as well as a diagram and instruction sheet (in .pdf format) that you can download and print out for you convenience.
