INSTRUMENT PANEL BACKLIGHTING

I have a 2009 Dodge R/T challenger, and I want to keep the theme black, chrome and red,

However my instrument panel has the blue backlight behind the tachometer, speedometer , gas gauge and engine temp dials. What is the part for the bulb system behind it?, I want it in red instead of blue, can someone point me in the right direction?
