Lighing Mods

Im sure im gonna sound like a noob asking this but frankly it isnt my car to mess around with its performance. My father bought an 05 L300 round thanksgiving and im finding the performance and sound system fine for what I need it. But Id like to make it look a little more stylish with lighting systems for the interior. I was hoping that you guys might have suggestions about what to do and what color would look best with my black onyx L300.
