I need reliable LED net lights with a dark wire in purple. They need to have a purple LED not just have a colored bulb because those always fade. I got these (http://www.amazon.com/gp/product/B007HCK14E?psc=1&redirect=true&ref_=oh_aui_detailpage_o09_s00) thinking they would be more reliable. Out of the box 2 of the 4 sets had 7 out between them. Now the other 2 have whole sections out. Those were expensive and I am really angry. It's too late to return them.
