Don't have any advice but just poppin' in to say that volunteers in our county, Polk County (Georgia), are not allowed to have ANY emergency lights on our POVs. It sucks...especially because whenever you are in the biggest of hurries, you get the slowest person on the road in front of you in an area where you can't pass 'em!
Everyone here uses POV with lights. A lot of lightbars but an equal amount of "undercover" led and stobes Our color here is red. There are flashers for LED that alternate I have one in my POV. Research them on the web. I am sure a local dealer is around also. My flasher came from West Chattum Emergency equipt in Augusta GA. It is a "ShoME" Multi pattern about $10.00
