Does the grapefruit stem have a lamp?

The second generation grapefruit stems have lights.

The middle end of the stem of the second generation grapefruit has a Y-shaped logo, the indicator light is placed under it, the mini indicator light is placed at the lower end of the stem, and there is a (YOOZ) logo on the stem.

The second generation of grapefruit will have a stronger sense of science and technology, with vibration reminder function and three-color indicator light reminder function. The grapefruit mini has no vibration reminder function, and the indicator light can only display one color.
