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 officers 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.

Smart flare vs. fusee

One smart flare replaces thousands of fusees

No smoke, no open flame, no constant relighting — just a reusable device that's ready every call.

★★★★★

"We have used the sequential flares on two different incidents. Both were fatal traffic collisions and they worked outstandingly. We are planning on using them for our upcoming DUI checkpoint."

"Pi-Lit is the cornerstone of my DUI enforcement routine. It offers features found in no other product. The unique sequential flash patterns help convey the direction of the police officer to road users well in advance of the DUI checkpoint."

"I've deployed them twice now. The first was a crash with rock blockage in a bad area — they worked great directing traffic and were easy to deploy. I watched a semi run them all over and they barely moved. The second was a 10-hour road closure; the -22° wind chill and snow didn't affect their function, and I feel our cones didn't get run over because of the flares. So far they've worked flawlessly with no hassle."

★★★★★

"For about 45 days our troopers have been testing the Pi-Lit 10 Set electronic flares, and feedback has been overwhelmingly positive. Easy to transport, deploy, recover and store on the included exoskeleton. The sequential lighting gives visual direction that motorists follow willingly, and troopers are using them in situations where they'd never place cones or single-use flares."
