When I started playing the game, I accepted the default green Pipboy color. As a result, when I turned on my Pipboy light, obviously the light had a green tint, which kind of hurt my eyes in the dark - I really didn't like it. So, for a while I used a miner's helmet, and loved the white light it produced. However, eventually I found a better armored helmet, and I couldn't justify keeping the miner's helmet, despite how much I preferred its lighting.
That's when I had a eureka moment, which many of you probably already know about. I went into my settings and changed my Pipboy display to white, instead of the default green, because I wanted to see what that would do to my Pipboy light. Low and behold, my Pipboy light is pure white, and easy on the eyes.
I am SO relieved!
Like I said, many of you probably already know about this. But if you were clueless like me, and would prefer normal-colored lighting when it's dark, I thought I'd share this
