I played in the configs a bit and figured out how to do this in case anyone wants to do a quick change while Eyamaz is on travel.Yeah. This was the original reason icy needles glowed something I forgot to fix inb4 the update.
You can add ,10886-78=12 to the end of the LightItems line in the DynamicLight_thePlayer.cfg and DynamicLights_otherPlayers.cfg to make your icy needles glow again.
The 12 is the light level. Torches are 15. I tried 12 a bit and it seemed sufficiently spooky in a dark forest, but the official update might use a different value. Also, I think dynamic lights is only client side, so this should work even if your server isn't updated (but I didn't test to be sure...).
