(Not the exact model used, but close)

Was rewatching the show recently, have a similar set of puck lights in my car for emergencies.

While watching I was very amused because I just happened to have one in my pocket from work today.

From ENT 2x04 - Dead Stop) at 19 minutes (incl. opening titles). Trip and Malcolm attempt to break into an advanced repair station, and decide to climb through an access port. But first they have to unlock the air filter...door. At least the station keeps its ventilation spotless.

Also obviously Enterprise D model kits because if they're using pens to make them then they're clearly making these on a budget. As for why the pod on the second design is circled I have no idea what it is, but according to the lovely guys at Ex Adtris Scientia it's part of an old Tomy toy. Credit to EAS for finding these... and everyone else who's ever looked at the first design because come on it is not subtle with the pens.

would anyone know what model car the brake cylinder belongs to?

I just noticed this on r/LV426. a cheap RCA jack with either electrical tape or heat shrink tubing as an individual soldier's microphone.

Can't find the actual brand online, but similar to the 2nd photo.
