Identify the lights?

Lines are camera/picture anomalies/defects. There are lines on the speaker too. Unity domes would not fit those lights, and the lines are at different heights on the domes.
In the top pic, the shape of the domes look like Signal Stat, to me.

I would say Signal-Stat 374 on the first photo. You have a conical base with a straight topped lens and four sealed beams that, for me, indicate Signal-Stat 374.

On the second photo you have a light with a rounded base and a rounded top lens with four large sealed beams that look like Unity RV-46 with Spitfire lens but I think its a ”mirage”.
The clear lines in the lens are on the wrong positions to be a Spitfire lens and I will say, as dmathieu says, that they are some type of optical effect on the bad photo.
The rounded base is shorter than on Unity and the sealed beams look like PAR46 but I think it is the metal lamp holder that make them look like that so they are most probably PAR36 ones.
I would guess that the light is Dietz 211/7-11.

Unity RV-45 with blue Spitfire lens.
The base is higher than on the photo and the lines sits higher up.

When I say rounded top lens on the second photo I think that it also is an optical effect on this very bad quality photo.
It is probably a straight topped lens.

But doesn't SigStat use Stratolite domes? Those are not flat? the only flat dome I know of is Sireno. Stratolite is slightly rounded, where Dietz almost comes to a point.

Dome shape and base shape lead me to think this is a Signal Stat dual 374 bar or... possibly... a S&W/Stephenson dual L-24 bar (rebranded Signal Stat)

Signal-Stat used their own lens with number 375.
It has a sharp edge between the side and the top which is more straight than the Sireno and Dietz lenses.

The Dietz 7-11 lens and the lens for Sireno 44660 look very similar to the Signal-Stat lens. They also has a sharp edge between the side and the top but the Dietz lens is more convex than the Sireno lens and Signal-Stat lens.

The Unity and the Stratolite 80 lens have a similar shape to each other with the rounded edge between the side and top.

The Stratolite 80 was used on several other manufacturers larger lights like Arrow & North American Signal.
