Rare Federal Signal Model 184 – CJ184 – CJ284 Motorized Replacement

Description

Rare Federal Signal Model 184 / CJ184 / CJ284 Motorized Replacement Unit

This exceptionally hard‑to‑find Federal Signal motorized replacement assembly is correct for Model 184, CJ184, and CJ284 applications. The black CJ speaker base can be removed, allowing this unit to serve as a direct drop‑in motorized light‑only replacement when the original CJ internals fail or when a speaker is no longer needed—significantly reducing weight while preserving full OEM authenticity.
Why This Unit Is Important
Federal Signal CJ models used a combined speaker + motor assembly. When the speaker fails—or when the restoration no longer requires audio output—finding a correct motorized replacement that fits the CJ housing is nearly impossible. This unit provides the proper OEM solution without modification.
Fitment & Compatibility
• Exact OEM dimensions and bolt pattern
• Perfect 3‑bolt drop‑in fit for Model 184, CJ184, and CJ284 housings
• Operates as a standard 184 motorized beacon once the CJ speaker base is removed
• Ideal for restorers, collectors, and film‑industry builds needing a correct, motor‑only replacement
