Remove blue object light.

[Googolplex]

Hello,
I want to remove the blue shimmer around items, when you want to pick them up.
Does anyone of you know what file I need to modify?
Is it a texture or a value? Please help me, perhaps Jens or Thomas know how to fix that.

It's just because I dislike item lights. I already managed to reduce the flashed lights, but I don't know how to remove the blue shimmer around them.

Thanks very much.
