Surf Fishing Glow “bobbers”

I see videos every now and then of guys absolutely launching their bait to the edge of the horizon. Usually it’s a night and you can see this glowing “bobber” of sorts being lobbed out to kingdom come.

What are they using or what would be similar in concept to use? I’m about to do some night fishing and I’m gearing up. I’m pretty new at this.

Thanks!
