Is something that has a glow in the dark component muktzeh ?
No, this would not make it muktzeh.
The Talmud, Shabbos 44a tells us that a lit candle is prohibited from moving on Shabbos. This is because the flame itself is muktzeh, and everything under it becomes a bosis [base] for the muktzeh, hence also obtaining muktzeh status. This is codified in Shulchan Aruch O:C 279. While there is much discussion as to the parameters of this halacha, that a flame is muktzeh, this only includes actual lights, such as incandescent, fluorescent,and even LED lights. These lights all are a matter of debate. However, a glow in the dark component, which is not lit, doesn’t go out, and is freely moved around would not constitute a problem of muktzeh.
