Hey y'all, I've seen this site before but just now signed up. I have been tinkering with 12 volt for almost 19 years. And started working construction a little over 9 years ago where I started focusing on strobe lights and have outfitted 5 of my own vehicles and many coworkers. What brought me to the site and finally sign up is I just acquired 10 light bars, 7 of them federal signal vista ricochet (non rotator), and 3 federal signal legend led bars. So the fun starts of research and testing.
