Blue trim LED very dim (blue only), need to replace

Noticed the side trim on my alienware (usually full blue) was very dim, I went into the AlienFX app and tried some other colors. Anything mixed with blue is over taken by the green or red led - so no purple, teal ect. My guess is the blue on the LED is buggered. What I need to know what style of LED I'm guessing an RGB-LED but what size and board or panel mount? Also where about on the laptop are the outside trim (#6 on AlienFX) components located..
