@LoreMaster This works, just tested it. It doesn't "Glow" until you prime the grenade (hold down LMB). Initially I thought it wasn't working, but then I realized that you have to prime or throw it to make it glow.
It would be cool to see it glow immediately and not require priming but meh, I don't know if it's worth the effort.
Changing the color to blue though, like the 'Blue Overhaul 1.5 - Laser Bolts for Every Weapon'

Anyway, thank you.
