Vickerman C7 LED Multi-colored Faceted Replacement Bulb, package of 25

I was looking for something different for Christmas decorations this year. I had a bunch of C7 strings that I wanted to do something with. started searching and found these twinkling C7 bulbs that are led. I have never seen twinkling LED bulbs before. I bought several sets and replace the regular incandescent bulbs with these. they twinkle so beautifully and they are quite bright too. they do not twinkle as fast as regular incandescent bulbs, however, they do twinkle fairly steady. I noticed other people had put in their reviews that they were playing at a pretty constant rate, however, I did not encounter that. it was most random. I did one of each color one after the other throughout the strings so I had constant flickering throughout the holiday season. Several of my neighbors came by and asked where I got them.

awesome twinkle and color ar any voltage
