Hey guys I was wondering how to create this type of image

thanks.

So you want to create your own colors for the lightbar?

This is a very good guide in my opinion: http://gtapolicemods.com/showthread.php?4023-How-to-Change-Lightbar-Colors

I know how to do that...i want to create that blue image..

It's a tool for Photoshop, think there's another for GIMP link: http://developer.nvidia.com/content/nvidia-texture-tools-adobe-photoshop

for the longest time the nividia developer zone was down thanks ridgerunner!
