Help with lights?

Not sure if this is possible but can a light be made to not pass through objects?
Here is a screen shot to show what I am talking about.
The light goes through the capsule and hits the wall behind it.
It’s just a spot light attached to a linerenderer.

Yes… Turning on shadows?

No shadows on a spotlight in Unity free :(.
I think I have a different solution.
I can use a red dot for a crosshair that is only enabled when the LaserSight is on. O.o
Or does that sound ridiculous?

Wait… If you have a line renderer, what do you need the spotlight for?

Trying to have a red dot at the end of the Laser Sight when it’s active.
I tried a few ways I saw on youtube but none of them worked for me for one reason or another.

How about a raycast, and moving a projector around?
