If you look closely at the pictures, you can see lights under the roof there. They're broken and have sparks (it's much more obvious in game). You can see them in the first picture. One of them is half-working (it strobes), so that's why the last seat is lit up in two of the pics.
I'm not sure what to do with the red lights. I like them there, and they give a nice feel, but they are much too ... bright perhaps? I dunno. Maybe I should lower the brightness a bit, or perhaps light up the track area a little so they don't stick out as much.
I quite like the cold light beam too. Simple light spots can build so much atmosphere, eh?
Thanks for the feedback, Captain, it is greatly appreciated.
