transparent/cutout/soft edge not changing to the directional light. How do i do that?

Ok, this is a vague question. But I will explain it! I have a tree. This tree has leaves on it. The shader of this tree is: transparent/cutout/soft edge (i dont know the full name of the shader). In the first scene in my game its dark. I have this shader on the leaves. I can make this leaves dark BUT! The player Has a flashlight if the player shines the flashlight on the leaves the leaves stay dark. How do i prevent this. I want the leaves are lighted if the player shines the flashlight on the leaves.
