You should check out NightOwl LEDs....they just released their Halo kit which you can add a grill light...it is quite awesome. I love mine.
Best part is I control it from my iPhone and the color choices and combinations are endless.
So if you are not feeling amber one day and want to run green, blue, pink, yellow, red, purple, white, nothing, ect the choice is yours!
