Federal Signal Thunderbolt 1003A | UnDulating Hi Lo Feat Glist | Bement IL | 9\6

Big thanks to Tony Price for letting us do this. So today I met up with the one and only ‪@Glist_‬ to record bements 1003A I pushed the button on fire and expected a normal hi lo but I got a better result when the bad boy did UNDULATING HI LO! I thought it was so cool. This siren is located at bement fire protection district station 1. Thanks Thanks for coming out ‪@Glist_‬!
