What do these lights show on weapons? (screen inside) (Fallout 4)

maybe this is a sight?

SIGHT the same.

The sight is a green dot))) And the red lights go out at the first shot and then they are restored again

ComeOnluMi,
I think so, this is something, like, a charge shot, isn't it?)

DielGood
then there should be 7 bulbs, while everything goes out immediately after one shot
In general, this is how it looks

Try it on enemies, maybe it's the power of the shot, 3 bulbs for maximum damage?

like the damage is the same, the first shot takes half of the health, the second is the same, maybe they are just for beauty? (although unlikely)
