Now this is pretty cool. I happened to stumble across this site due to a Google Adsense Program link on my own site.
SolarSanta.com by MRLIGHT has a number of solar powered LED christmas light sets. Pretty neat idea for putting lights where you don’t have an outlet. The only downside is the cost but I guess, if you have to buy a super long extension cord in addition to your normal LED lights, the cost might come out much closer.
