DIY Outdoor Lighting Installation? I want to put decorative lighting on the front of my house....

I want to put decorative lighting on the front of my house. The sidewalk from my entrance lead out to the street and decorative lamp are on the house on each side of this waddle...pretty std stuff. Should I tap into electric wiring going to these lights....or should I create a whole foreign source? I hate to own to route wire underneath my sidewalk if I don't have to. I will probably put 3-4 lights on respectively side of the front part of the house. Thanks

Answers:    Been at hand done that. Low voltage lighting is a snap to install, versatile and economical and an awesome nighttime effect. It will bequeath you great satisfaction for the investment but requires burying the biggest cable to look decent within the daytime. THEN.. after awhile the whole system starts going to crap and it become more trouble than it's worth. A 110 volt set-up is more reliable, still requires digging, and SHOULD be installed professionally and is potentially dangerous. They are practically giving away self-contained solar powered lights that you lately push in the ground where you want, cost nothing to operate, and can be replaced as efficiently, (and almost as cheaply) as a light bulb. Which one do you estimate I'd recommend?

get the reading light kits from lowes or home depot, they run on 12 volts. they are cheaper and safer to use. afterwards just plug them into an outdoor plug.
