Boy are you gonna be opening a book for that question lol.

Youre gonna get a mix of responses saying a certain one is an effective one, while someone else may say a different pattern is effective.

Personally i think any flash pattern is effective no matter what brand of light it is........yes even the knockoff stuff has some effective patterns :)

Whelen's 2 most effective patterns, based on "on-time"/brightest pulse per flash, are single 75FPM, ans SignalAlert 75 FPM. These 2 provide the longest on time, hence the brightest flash. The NAAFPA specific L31 lights have these 2 pattrns only. I tend to use the SignalAlert because it uses the combination of rapid pulse and long on pulse. I also use cruise when flashing, giving a "never off" signal.

I like signalert 75, very similar to a brake light pop. Actionflash has its perks too, strobeish pattern alternating with slow single flashes. Good for side warning.

And yes you've opened a pandora box with your question ;)

Whelen has redesigned their website, renamed their aviation business, and now all links to their flash pattern generator have disappeared.
Not only the flash pattern generator but the page with light bar manuals, lightheads, serial products, everything, now it's just the current lineup, a facebook link, the divisions are now red, blue and amber, and the literature is pdf numbers no names... WTF is that. I actually sent them an email cause I was so disgusted that all my webpages I bookmarked are all dead I can't find anything to use for reference material even the siren tones is a zip file.

I wondered why my flash pattern videos have seen an uptick in views......
