The middle "Lines" version is the only one I care about really in case that helps: https://assets-mod.factorio.com/assets/11232a568b83f4e14ea2dd5611e46231a02ef29f.png

Yeah, came here to suggest the same.
I'm using Arrowless Belts and think it would just make the game really shine to have that one, plus this, and the Black Rubber mod all together.
Would that be possible? :)

Not only that, but the mod also features toggleable glow options for arrows. So, you can have a glowy middle lines on your belts! Check it out :)
