ETD has the worst customer service that I have ever experienced. May God help you if you actually need a warranty replacement or technical help.
Plus, a few fire dept personnel had their lights and they are crap. Cheap quality with short lifespan. And most emergency lights (except whelen, soundoff, and maybe fed sig) are made in China, but the ETD lights are literally bottom line throw away junk. Can’t trust them with your life, which is why I don’t understand why people buy them.
Fyi- regarding Strobes n More. I ran their dual color E6 lightheads for 3 years and they were great lights. Didn’t fade or lose intensity. I sold that vehicle, so now I ordered an amber TA (SNM E66 Mini) and I’ll throw some Whelen Duos on the ends of it.
Lastly, Whelen (big 3) > SNM,Feniex> Speedtech> ETD. That’s my opinion.
