From what I have seen eclipse and pioneer have some units that light blue but they aren't double DIN unless it is an in-dash DVD/CD player. Crutchfield lists lighting color too I believe, some head units you can change the colors of the lights. Crutchfield is great for using as a reference to see what you need, but unless you buy everything as a large order and take advantage of the discounts it can get expensive. The adapter harness is pretty expensive for what it does. I bought one for my old impala to adapt for chimes and onstar and it was $100, the malibu costs more depending on your factory options. Plus, the stupid module failed after 3 months and I couldn't get them to send me a new one (metra).
