Using the collected reference images I found on Pinterest, I started my model which was a Japanese LED siren of the Patlite corporation, spending a couple hours everyday was able to get most of the model complete. If I go further with this model, I would include several more details such as the LED internals and back wall. And finalize the model in Keyshot.
