Wire Lamp Bug

Short and Sweet. When I spawn a wire lamp, it projects light from the front and rear of the lamp model. Why and how to fix?

Do you see same problem with vanilla Garry’s Mod lamps?

Pretty sure it’s meant to do this iirc.

In the previous Gmod 12, they did not do this.

Well wiremod is still being worked on atm, especially render and draw stuff.
I would ask on wiremod forums, they would know.
