Ghostbuster Siren for Model and RC Cars Same Siren from the Ecto 1 Car in the Ghostbuster Movies! Runs on 9 Volt Battery Wired and Ready to Use!

Ghostbusters Ecto-1 Siren This siren is the same as the Ecto-1 siren in the Ghostbusters movies. You can listen to the siren in the video by the reviews section of this listing, or by searching “Evan Designs Ghostbusters” on YouTube. The siren’s circuit board is about 20mm long, 11mm wide and less than 5mm thick. The speaker is 36mm (1.4 inches) in diameter, and 6mm thick. The siren speaker is wired 7 inches from the circuit board. The switch and power leads are 8 inches long. Includes a battery strap with 2 on/off switches (shown in the photos). One switch controls the siren, and the other switch is for any LED lights you want to add (Additional lights not included). Powering your siren: The siren can be run on a 9 volt battery using the included battery strap, or on any 9-12 volt regulated DC adapter. Note: Not suitable for outdoor use. (Larger speaker options coming soon.) If you do want to use this outdoors, you can solder the 2 speaker wires to a larger speaker. If you find the larger speaker causes your batteries to die more quickly, you can connect the siren directly to the vehicle’s battery as long as it does not run at more than 12 volts. Often times batteries will be 1-2 volts higher than the value listed on the battery when the motor is running. In this case, you will also need to add a small resistor to the red power lead of around 100 Ohms.
