What is this?

[Spruslayer]

I am in the middle of this kit

On top of the sleeper cab there is a round thing that kinda looks like it might be a light

Its hard to see in this view but if you look between the drivers side exhaust and the cb antenna on the roof of the sleeper.

Can you help a guy down on his luck

Could that be a communications antenna? Maybe for GPS or satellite radio? Just guessing, here.

Here's one I found while looking around:

There were no GPS systems back in the day. I'm pretty sure that's a vent. The aerodyne had a roof fan and vent assembly, kind of like an attic fan. Here's an inside view.

Thanks brian!

My quandary was that if it was a light i was going to paint it,but now it shalt remain body color

Back to the bench!

I'm pretty sure that I've seen them polished as well as painted. I don't get to see the roof too much.

I always thought that was a vent but I wasn't sure.  Thanks for posting the article. I love reading the articles from back then.

Bucky, I'm curious to see where this goes as the W900 Aerodyne has always been my favorite truck. The kit represents a '76-'81 and GPS tracking systems first showed on trucks in the late '80s.

It's a vent.
