Been wondering about this since I can not find anything on the internet or studies about this. People who buy aftermarket dash light there are always a ton of flash patterns for these lights.  I was curious on the visibility/ noticeablility factor of the flash pattern of say a standard red/blue combo. 

Is it better to have a single color flash? Dual color flash like a in out pattern? I am assuming the flaster the flash the more visible but at the same time it can be too fast. 

Any opinions or experience? Studies? Please post. I am curious.

Again not worried About the factor of being combined with a overhead unit or additional interior lighting. Soley the dash its self, say if you were to run it as a stand alone.

I was hoping to search the internet and find something... funny thing is there is not really anything that I have found. If you guys know links please post them.

Since we can't post links, use your search engine for "Code 3 Lights", "Whelen Lights" or "Federal Lights".      

Galls.com carries most brands, but the three lights mentioned are all popular law enforcement lights, just to mention a few.

 

Unfortunately none of the sites have anything posted I saw. They have information about their products which is not what I was lookign for.  Wasn't looking for dash lights, was inquiring about the noticeablility/ visibility of flash patterns and motorists.

 I'm not a police officer yet, but I've been working for a school police agency directing traffic, and have had legal warning lights on my personal and work vehicles.

I can't speak as to responding lights and sirens, of course.

But when I need to slow down traffic to a school with 4,700 students, I change my flash patterns every few months in order to keep regular drivers from thinking that the same old flash pattern means they can start driving irresponsibly.

I've noticed that in rainy or snowy weather, a slow wig wag flash of my lights is best. It seems that when your vehicle is parked, a really fast flash pattern makes people drive quicker. I would recommend a pattern that scrolls through different patterns because based on different situations, drivers will respond in different ways. 

Currently, my dash light is set on a medium speed wig-wag, my rear bar has a directional pattern, and my rear auxiliary lights have a slower warning pattern.
