Our mission since 2013
Bring our first responders home safely every night
The roadside is the most dangerous place you work — so we engineered a smarter way to own it. Smart sequential flares turn a chaotic scene into a clearly-directed one: more warning, earlier, and the buffer your crew deserves.

Our Sequential Flares exists for one reason: to put an unambiguous "arrow" of moving light between you and oncoming traffic, and get everyone home safe each night.
How it works
A runway of light, laid down in seconds
There's a reason a sequential "rabbit" beacon guides every aircraft to the runway. A moving light reads as a direction, not just a hazard — so drivers slow down and move over before they reach you.

01
Pull Off & Drop
No programming, no pre-numbering, not having to search for and hit a button. Simply pull the sequential flare off the case and place — the flares auto-sync into the correct sequence as you walk the taper.
02
Warn & Guide Traffic
A moving "runway" of light reads as a direction for motorists. Drivers see it further in advance and distinguish the active moving light from your light bars — reducing and preventing any confusion or disorientation a motorist experiences when entering a chaotic scene.
03
Grab & Go
The Endoskeleton case makes it easy to retrieve the sequential flares. Leave them flashing as you snap them on the case - keeping you visible to traffic until you get back to the safety of your apparatus.
From the field
See a real scene get lit and cleared
Turn and drop. The flares find their place in the sequence on their own — no programming, no pre-numbering.

From the departments
Run over, dropped, beaten up — still going
★★★★★
"Our department ordered these about two years ago and we couldn't imagine not having them. If you respond to accident scenes or close roads often, these are a must-have. Very easy to use and very effective — we now run them on all our fire engines as well as command vehicles."
JB
Lt. Jonathan Beam
Winchester Fire Department · KY
★★★★★
"Our firefighters deploy them on accident scenes, for air-med landings in the field, and to direct traffic during structure fire operations. They've been run over, dropped, beaten up, and put through every test of firefighting operations — and they're still going strong. One purchase we are absolutely thrilled with."
DR
Chief Dylan Riedel
City of Russell Fire Department
★★★★★
"The lights are great and have worked extremely well out on the highway. Other agencies have asked about them and really liked them — the troopers talked about getting them instead of flares. Great purchase for us, and great customer service too!"
BB
Brian Bohlsen
Jordan Fire Department
★★★★★
"I ordered a set to test with my night driver and our safety department absolutely loves them. I've been authorized to order four more units just for our division's carryall drivers. Safety is the most important culture in our business."
