Time to pass this one on . I do not know a bunch about light bars but I collect them anyhow , will do my best to supply pics if needed . This is a fully functional light bar ( rotors /bulbs all work ) Sale will include the Red/Blue domes as pictured . Basically a late 70's - mid 80's Federal Signal TwinSonic Police light bar . Light bar does not include siren horn . Due to age (previous owners) light bar could use some cosmetic TLC . The Red/Blue domes do have cracks ( not structural ) just cracks . I am guessing from ++ tight screws . VERY COOL ADDED PLUS......THIS WAS A LOCAL PD LIGHT BAR . IT BEARS A CITY OF ST. HELENS PROPERTY ID PLATE W/# . I AM ASKING $150.00 OBO with local pick-up (Molalla) preferred . Bulky item to be doing errands in my compact car . My only trade interest is in steel cased 223 ammo (brand?) possible for brass cased factory 223/5.56 if priced reasonably . Shipping this would be time-consuming so , no thanks .
