California Special model 7-120 - Ever Seen?

That's pretty interesting, so its 2 non rotating beacons with 3 par 46 lamps. the Odd lamp acting as a possible alley light.

I don't think I have even seen a Par 46 Dietz beacon even not CA spec.
 
I have never seen these on any units in CA. And they had to run the PAR46 bulbs in order to meet Title 13 back in those days for steady burn and rear flashing. Those are very unusual, the concept however isn't bad, many of the CA agencies that ran one single revolving light in the center would then place two rear and two forward PAR46 on the ends and some the speaker right next to the rotator of the roof rack blocking 50-75% of the side warning light.
