This could be easily acheived by doing the following steps:

1. import the image you wanna do this to.
2. make a new layer, and make it a mask layer.
3. make another new layer, and put it under the mask (Make sure it is indented, otherwise, it is just a layer, and not a masked layer)
4. on the mask layer, draw lines with the brush, not pencil, where you want the 'flash' to be. make the line size 2 or 3.
5. on the masked layer, draw a rectangle either the same height, or a bit taller, as the image you are working with.
6. fill it with a custom colour gradient. make it linear, and have a light colour in the middle, and on each end, a dark colour (use the same colour for the best effect)
7. Convert this rectangle to a movie clip, and tween it. make it move from whichever end you want the flashing to start from, to the other side.

For best effects, make the whole thing about 60 frames, and use 30 fps.

enjoy.
