Another popular choice - Rope lights

Rope lights are beneficial in that they are very easy to wrap around deck or porch railings, or around columns on porches. They also look very nice around windows on garages or tool sheds for extra holiday flair. They can be bought in spools of between 12 and 30 feet. Measure first, to get just the amount you need. Rope lights emit 50% less heat in addition to saving energy; they only use between 3 and 6 watts. Don't worry about competing with your neighbors. It's not a contest; it's being economical.
