What cause these lights to blink?
The final two christmas i do not put up my tree since i do not have the time to however i don't know about this 12 months yet. And i like them nonetheless because i do not like blinking lights
They probably have a blinker in them that makes it do that. Look for a clear light with a red tip and take it out replacing with a colored one. If thats not the case you may have a light burning out effecting the whole string.
There probably a bulb that is clear with a red tip that causes the string to blink.
