Pre-lit Christmas Tree Lights Keep Blowing Out

I have a small mini pre-lit tree that has only one strand of lights on it. Half the section has blown out (bulbs had black parts surrounding the inside). I tried the Light Keeper Pro and it didn't work. I ended up replacing every bulb and the lights came back on. A few days later they stopped working again and I noticed all the bulbs had black on the inside again. What could be causing all the bulbs to blow at once? Any suggestions (besides stripping all the lights off and adding a new strand (which would be a brutal step).

Different micro amp on bulbs you replaced. They should have looked brighter than original bulb.

Too much amp for bulb so it burnt out.

I have one of those trees also. I don't use it a lot. I found some answers here if you would like to look through them:

I hope this was at least somewhat helpful. I wish you a Merry Christmas and a Happy New Year. Let us know if you find out what it was that caused this.
