Light In The Dark Theme is for the new CM Theme Engine duced in CM11. You will need to have a custom Rom that supports the CM11 TE installed on your phone or tablet. CM11, PA4+, and AOKP are some examples of the custom Roms. As many themers are focusing on L design I am doing this for those who loves the DARK SIDE.
