Does anyone recall what lightbar the Sacramento Co. Sherriff's used in the 70s?

[1968]

I saw this film while I was procrastinating online and I saw this unique lightbar setup on the Sacramento County vehicle I never saw before. I'm curious as to what it is? The quality of the tape is bad but it looks like it could be a Visibar with an electro mechanical siren alleys and a can like light in between the two beacons and the siren speaker. Perhaps someone here may recall what equipment was used during the period.

Federal Twinsonic CTS.
The one you may mean looks like a Unity RV25 beacon.

Cool video! I agree, the 2nd cars beacons look like Unity RV either 25 or 26.

I agree on the Unity.
But WOW, that video reminded me of those old Motorola training films they showed
us at the Police Academy back in the 70's.

I can see and hear a Unitrol 800 in the video.

Looks similar to my Unity Unirack II setup!

They MAY be Unity RV-25. The RV-26, 45 & 46 used a larger base/dome. 26/46 used PAR 46 bulbs (5.75” diameter). The 25 & 45 used PAR 36 bulbs (4.5”).

That said, Unity did not have the strait chrome can lights and those are not UniRack bars…the gutter clips rested flush to the roof.
