Here is a slideshow and video of the now removed, previously abandoned, Federal Signal Thunderbolt 1000AT in Eau Claire Wisconsin. Found these files on an old SD card I was cleaning off. Siren was installed in 1984 and was abandoned in place when the new system was installed around 2000. Siren was removed April 2016 and attempts made to acquire the old relic were unsuccessful.
Thank you for watching. Please leave a comment, subscribe and like this video! -WiS&S(JMAN)
