I recently visited the San Diego County Sheriff's Museum in California and saw they had several emergency lights on display. They had a CTS bar, an Aerodynic bar and a Vision bar. The oldest light they had on display was this Federal Signal beacon with the California steady red light attached to the front. Unfortunately, someone felt they needed to paint over all the chrome with white paint (possibly to match the white roof of the patrol car). The badge was painted over so I couldn't get a model or serial number on it. There were some pictures of the light mounted on patrol cars that didn't appear to be painted white, so I'm not sure why this one was. At any rate, I thought it may be of interest her on elightbars.
