http://gtapolicemods.com/downloads.php?do=file&id=497 or would it be possible?

or can someone simply make the lightbar on the trailblazer in the colors on the front appear as Blue, Red, Blue,White,White,Blue,Red,Blue and on the Rear of the lightbar would be Blue,Amber,Blue,Blue,Blue,Blue,Amber,Blue Please, These Are the Colors the Washington State Patrol Use :D

They have the same bar? Also, the trail blazer would be locked. You need to change the els colours.

There is an unlocked version of the trailblazer in case he wanted to make it himself.
