This file includes 14 light strokes (light trails) with transparency. All light strokes are on psd layers (1920px * 1080px).
You can change every color and composite all strokes the way you want. All strokes are on transparent layers. They work perfectly on dark backgrounds or pictures. You can also combine them with graphic elements like the headline on my preview image.
The file is very easy to use. It requires Photoshop CS3 or higher. A layered .tiff file is also included.
