The Federal Signal HighLighter is a 2-head rotator beacon intended for work trucks (or volunteer firefighter vehicles, or something of that nature) that want a bit of style, since, let's face it, Federal Signal is the Mercedes of emergency vehicle equipment. It's also intended for tow trucks however it only has 2 heads so not the best option. Models that have a diagonal mirror between the heads can produce up to 380 flashes per minute. It is available in permanent and magnetic mounting options. It's roughly 15 inches in length.
All HighLighter models meet SAE J845 Class 1 requirements (SAE J1318 Class 1, 2009).
Agencies that use it:
Anybody who has a work truck or volunteer firefighter vehicle, POV, or things along those lines. No real police agency will use a 2 head rotator... Maybe on like a John Deere gator, but only beach patrol uses those type things.
Amber, Blue, Clear, Green or Red. No purple for those who use purple (which is like nobody).
