While headlights installed inside a pool are pretty awesome, the Ocean Art Light-Up Jellies will add a more vibrant and colorful aesthetic that is much safer and follows the same concept.
The Ocean Art Light-Up Jellies are a cool, decorative piece for the pool which will make it a lot more interesting to look at. The head of the jellyfish gives off a multi-colored glow while the tentacles dangle beneath the water. The item uses LEDs as its main source and requires batteries to operate. These are for decorative purposes only, so if you're actually planning to rely on these as a light source for late night swimming, actual headlights in the pool would be a better option. Still, these do bring a nice glow that anyone can appreciate.
