I'd stick with the original design -- it just seems most minimalistic and simple, unlike the ones provided above which don't really fit the visual style of the game -- despite being realistic.
It's basically just color replacement (red is now white), but unlike Bethesda's green, it should be more visible when you actually use them in game.
