the question is clear but may not be what you're really asking. You cannot place a light source outside the window unless you build the scene in Motion's 3D space. You have an interior shot, you need lightning to appear to be flashing outside the window. That would not illuminate the entire scene, necessarily, but it might cast a hard window shape onto the floor or the wall. Draw a mask shaped like the window, with the curtains and mullions, and distort it in perspective and place it on the surface.Illuminating it can be done many ways and I'll leave you to discover them. However, remember that lightning is an instantaneous discharge, like a photo flash, not a light bulb. And yet the convention for film and stage lightning is more like the ramping up and down of an incandescent lamp. Horror movies tend to use only one or two frames of lightning flash, accompanied with a cut to a closeup, to illuminate the threat in a scene and then a cut to a reaction shot of the protagonist.
