Review on CHANZON 100Pcs (10 Colors X 10Pcs) 3Mm LED Diode Lights Assortment (Clear Transparent Lens) Emitting Lighting Bulb Lamp Assorted Kit Variety Colour Warm White Red Yellow Green Blue Orange UV Pink by Tyler Munajj

I bought to try to repair some LED xmas light chains. Unfortunately, there's a little "flange" around the base of the "bulb", prevents them from inserting fully into the colored cover. This wasn't really visible on the photos in the add. Used a Dremel to grind off the flange, then they worked fine. I made a little LED bulb tester with a button battery (2032) with wires held on by a metal clip, since my incandescant "Lightkeeper" won't work on LED light chain. However, the no-touch voltage tester function in the lightkeeper works on the LED chain. Overtall I'm satisfied.
