you can do it in easy 3 steps: Step 1 : Open a new file by clicking on File > Open. Create a new layer. Step 2 : Open a image by clicking on File > Open. And select the image to your new file canvas. Step 3 : Now to create different lighting effects go to Filter > Render > Lighting Effects. Choose the style and Effect that you want for your photograph
You could also make a new layer on top of the car layer and place a white soft brush on the place you want the lightning to be and then lower the opacity of that layer
