hey everybody i need some help.As you can tell by the title i am possibly getting a FS aerodynic lightbar from a buddy of mine. this bar has a rotator light system in it obv. for it being an older version of the bar. i wanna update it to LED and i have no idea where to start. this is where you guys and gals come in to help me. i went on FS website and i maybe blind but i didnt see the light system they are now using in there new version of the bar AeroDynic Lightbar - Lightbars | Federal Signal that is the link. i dont have to use FS product but i wanna put something in it that is gonna last and fit at the same time. i also need to get clear domes, the ones on it now are colored. Any help would be great thanks.
