I made a lighting system previously (This). For what you want this doesn’t work, but the system can be slightly modified to work like a flashlight. Normally the system would cover the view, but if you reverse it will act like a flashlight. Normally if you wanted a 60-degree view it would cover that, but if you instead have a 300-degree light in the opposite direction it will work like a flashlight.
There is a problem with this, in the direction that you can see you will be able to see until the edge of the screen.
(I probably did a bad job explaining this so just @ me if you want me to explain something in more detail)
