As quite a few of the responses are, it's more about the performance than the looks. but I think that the ADT Clear Warning is probably the ugliest. It also lacks in performance, which is an added bonus.

Apparently no one has mentioned this system before. There are only 3 sirens that were installed in 2000, and it's only intended to cover the Union Pacific Rail Yard in Roseville.

This is my map of sirens in Alaska. I've never posted anything here but I am semi-active on ARS discord, and my tag is #1800 since I change my nickname pretty often. Feedback is appreciated.
