[Creating a "backlight" texture.]

Thank you both for your answers. I have found both very useful and after having a play around with both I found TrevorOutlaw's method the most effective 

[Creating a "backlight" texture.]

Hello all,

 

I was wondering how to create a texture similar to this in Paint.net:

How I plan on doing it (unless someone advises there is a simpler way of achieving it!) is having the "Bus Stopping" text as some kind of cut out into a plain, black layer and then having the orange backlight on a layer under that. I am unsure of how to create this light though. Can anyone please recommend any plugins or methods that may assist with this?

 

Thank you in advance
