Increased green glow with increased radiation level

[CitizenFurin]

That's pretty much it. The more rads you have got, the more you glow (in steps, 200, 400, 600, 800, at 999 you begin to blink xd). I have no modding experience but could maybe done with a duplicated pip boy light in a different color? Could also make hiding more complicated but once you have 600 rads you won't need a pipboy light in a dungeon any more.
