How do self blinking LEDs work?
The circuit for blinking an LED using transistors is called an Astable Multivibrator. The two capacitors C1 and C2 will alternate between being charged and discharged and thereby turning the transistors ON and OFF. When a transistor is ON it allows current to flow through it so that the LED above it will light up.

Short Answer: Your LED Christmas lights are flickering because they aren’t built with inline rectifiers. These full-wave rectifier circuits (diode bridges) flip the lower half of the input electrical waveform which results in a higher rate of flicker that virtually disappears to the naked eye.
How do you make LED lights blink slower?
Most circuits use resistors to control LED blink rate. Once you find where the resistors that control the blink rate are located, you can adjust the resistors’ value for a slower blink rate. Obtain the schematic of the LED flasher circuit you want to stop the LEDs from blinking too fast.
