I had a feeling that was your high-beams that were missing!

You've also got it right for the unit on the roof - that's the AC. It was an option from GM installed on buses in warmer climates.

My brain must not have processed part of that comment properly about the missing part before, so I'll address it now... I created, via XML editing, a slightly more powerful version of the "in-block" small spotlight for use as a proper high-beam headlight on this type of vehicle. Thanks for letting me know it isn't working; I'll put in a regular spotlight for now.

@End of the Line: Thanks for checking it out! I'll try to make it Stormlink-compatible in a bit; changelog will show it when I do.

Curiosity question: what purpose would the unit on the rear roof serve in the real thing? I'm guessing air-conditioning, but I'm not sure because I've never seen anything like it in any pictures.

Thanks for providing proper credit for the windows! I'm impressed with the modular engine and exterior light details, really captures the feel of these vehicles. I think the inner headlights may still be a missing modded part - there's just an empty space on my unmodded system. If you make this compatible with Stormlink, I'd be happy to include this as part of the Stormlink fleet collection!
