I am currently working on the engine but I also pay attention to the lights, I think that the headlights are the "generally most important" part of the car as you would rather look on the car from it's frontside than it's rear. These headlights are re-worked Juiced2: HIN ones and if there's someone who wishes to have them you may ask for them in the chat.
Stay tuned for some madness, custom parts are being progressed and will soon be published for you to look at.
