The weirdest looking siren IMO is the ACA allertor. For scary sounding, any dual-toned Thunderbolt. For scary looking, Thunderbolt series. looking at a T-Bolt from just the right angle can make it look very menacing! Especially when sillouetted by lightning!
Federal Signal Thunderbolt Series, still the King of Air Raid Sirens!
