Its none of that.......I got the 100 off of ebay too,and am having the same problem.They just go out all the time.I got tired of pulling everything apart only to have the other one go out the next day.Its a bunch of bunk LEDs.We got what we paid for.I went ahead and bought some good ones about a month ago and havent had one go out yet.
The ebay ones are good for something thats not going t be lit up alot.Like a flashing alrm light or the light on your alrm remote etc.
