Since I'm probably not going to be building an Ectomobile any time soon, I made this fun little box that clips onto my belt. The only thing it does when the switch is flipped is flash a blue light and play the Ecto-1 siren sound. I used parts intended for a model kit and some generic greeblies, plus a couple of enamel pins on the front. I have no idea what it would actually be in-universe – some kind of beeper? I just wanted something I can switch on to make the siren sound.

I love this idea! how did you make it light up and play the sound?

Damn, nice job!

I used this kit: https://evandesigns.com/products/ghostb ... bb15&_ss=r

The speaker is plenty loud enough to not need grill holes in the box. The blue cap is from DigiKey, and the power toggle is an accurate one to a Ghost Trap. This was sort of a practice project for learning soldering.
