Description
Federal Signal Model 12 / CTS TwinSonic Light Bar
This Federal Signal Model 12 / CTS TwinSonic Light Bar features classic red domes* with a rear amber flashing warning insert. It also includes the solid red, forward‑facing PAR‑46 headlamp required under historic California statute. Opposite the solid red is a rear-facing flashing amber light with special amber cutout on the red dome. The unit comes with 2 feet of red, white, and black primary leads. The forward red beam can be activated independently using the white lead if desired.
We also offer the option of replacing the forward red dome with a blue dome of equal quality. If you’re interested in that configuration, please contact us through our site’s messaging tool for details.
This CTS runs smoothly with strong cosmetics and excellent dome translucency — a true vintage piece of California emergency‑vehicle history. Please note: the top of the siren cage once held a police antenna; the hole has been professionally plugged and is now barely noticeable.
