Flashlight doesn't work on a specific angle

[lenny0]

So I am making flashlight in my unity 3d project, and I saw that it doesn’t work on one specific angle. It doesn’t work in game and also on the scene. It’s just an angle, where flashlight almost doesn’t flash at all… Pictures below
thanks for help

Works perfect and moves with the camera

And this is the point where it stops working
It works but not on the other side

Im still a beginner so i dont know how to fix it
EDIT: It looks like that it does work on the first 180 degree angle but not on the other 180 degree angle
