Here is the build thread for mine:

I had a stab at doing custom lights for it but it doesn't look like I posted any of the pictures, there is a light box on the back of the cab pointing down to illuminate the chassis, and then there are lights for the front giving you headlights, fog lights and running lights.
I need to dig it out at somepoint and do some rework on it.
