I find myself hording Daedric Arrows because they're so rare and valuable that I don't want to actually use them and risk losing them. So I made the fins glow a bright red, making it much easier to find and recover them. They also look ubercool on the PC's back, as the arrows in the quiver also have red, glowing fins.

Bound Arrows are based on the Daedric Arrows, so this will effect them too. However, the effect is rather subtle. Not that it matters, since you can't recover bound arrows anyway.

This is a mesh and texture replacer; there is no ESP, so load order is not an issue. Any other mod that replaces the Daedric Arrow meshes will conflict with this mod, though probably not catastrophically. Whichever mod you installed (not loaded, INSTALLED) last will win.

There is now a version with a glowing aura as well.
