C9 Blue / Cool White OptiCore Commercial LED Christmas String Lights

I got tired of buying new lights every year. These things are heavy duty. I expect to have them for years and most likely will save money over buying cheap lights year after year. After viewing the quality of the lights I bought a second set.
