Why does remote control seem not work when I adjust the string light? In flash and breath modes, pressing + or - will not adjust brightness, only speed can be adjusted, and brightness can only be adjusted in static mode. Why does the solar string lights light up and then turn off again or have flicker problems? Because the solar panel has a light sensing function, if the solar panel is directly under the light string, once the light string is light up, the solar panel will mistakenly think it is daytime and turn off the light string. Why does the string lights display full charge but not light up? Our Solar string lights has dusk to dawn function, which automatically turns off during the day and on at night. If the external environment is too bright, string lights may not light up. Why do the solar string lights go off after 6 hours? Our solar light string has a 6-hour self-protection automatic power-off setting to prevent the battery from running out too much and losing power quickly. If it goes off, it can be turned on with the remote control and used normally again. What is the after-sales service like for this string light set?
