Add a Realistic Fire Truck siren sound to your Model Fire Truck!
This fully assembled circuit with speaker has a siren that plays the long wail plus a few bursts of air horn.
The siren has no switch, we include a battery snap with 2 switches free with the 9 volt battery version of this unit.
The great thing about 2 switches is you can use one switch to turn the siren on and off and the other switch for any lights you want to add.
You can have siren only, lights only, or run them both together for awesome realistic action!
