Sequential Barricade Warning Lamp

Pi-Lit® Sequential Barricade Warning Lamps enhance safety for work-zone personnel as well as motorists entering the work zone. Much as a pilot is guided to the runway by the sequential flashing strobes (“rabbit”), sequential warning lamps aid the driver by guiding them safely through the work zone.

Drivers approaching the work zone are often  confused by the number of flashing lights, vehicle light bars, and “flood lamps” located in the work area. The Pi-Lit® Sequential Warning Lamp is designed to help prevent work zone accidents due to driver confusion. These  lamps mounts on any drum, vertical panel, or barricade, and communicate with one another to form a smooth and calming pattern that guides motorists safely through the work zone. 

A number of studies have shown that the use of sequential warning lamps at the entrance of a work zone reduces vehicle speed and enhances driver compliance. Drivers approaching the work zone see the visual warning and guidance which results in earlier merging and slowing, thereby reducing the chance of incident.

SAFER WORKZONES

REDUCE DRIVER CONFUSION

"Moving" light is more effective at alerting and guiding drivers than random-flashing stationary patterns. Drivers are aware of activity ahead but are disoriented and confused by the cacophony of vehicle lights bars, flood lights, warning lights, etc. Enhance the safety of your team by using sequential warning lights.

Increase Driver compliance

Sequential warning lamps alert drivers further upstream. This results in a speed reduction as well as earlier compliance with taper.

Lowest Cost product on the market ..and with the most features!

As the new kid on the block we try harder. Six years later we remain the most advanced product available and the only one with remote control capability, multiple pattern choices, reversible patterns, simultaneous flashing of all lamps, and many more.

BARRICADE AND BARRICADE S

Barricade

5 button version with all features programmable by buttons on the lamp and by remote control

Barricade S

3 Button version with simplified membrane-switch for ease of use on the roadway. all features are still active and controlled via remote.

Simple yet intelligent

Intelligent radio technology automatically position barricade lamps in correct sequence making deployment simple and quick. No Master Slave; No infra-red limitations. Just mount and turn on. That simple.

industry leading battery life

Powered by 4 alkaline D-Cell batteries. ~4-5 months continuous-flash battery life.

Versatile

The novel technology provides many options, yet is simple to use. Supports tapers (lane closures) of any number of lamps. Can be deployed in any shape (circle, linear line, around corners or bends, etc.)

500 ft (150 m) range

The radios will communicate across 1000 feet, but to maintain the network we recommend a max 500 feet range (152 meters) between lamps. As long as one lamp is in range of another the message will get passed along. This means you can have miles of lamps and the sequential network will still communicate.

BARRICADE MESH NETWORK

Control All from one

Any one lamp controls entire network of lamps. Changing a parameter such as pattern requires the user to press a button on one lamp. That lamp will send a message to all the lamps in the network. In addition, no need to turn off each lamp. The user can do a "group off" from any lamp or remote control and all the lamps will turn off.

5 patterns

There are 5 flash patterns to choose from. Four of the patterns are sequential and the 5th is simultaneous flash. Please click here to see the animation of the patterns.

Group frequency channels

The are times when you deploy 2 or more sequential tapers in close proximity. Now with our easy group channel programming feature the operator can change the group channels on multiple sets at once.

SPECIFICATIONS AND FEATURES LIST

Specifications:

Features (Mechanical):

  • Intelligent radio technology automatically position barricade lamps in correct sequence making deployment simple and quick. No Master Slave; No infra-red limitations. Just mount and turn on. That simple.
  • Operates in a "Mesh" network using 2.4GHz radio communication. Not affected by weather (rain, snow, fog, or other obstruction).
  • 1000 feet range (300 meter) between lamps. As long as one lamp is in range of another the message will get passed along. This means you can have miles of lamps and the sequential network will still communicate.
  • Supports tapers of any number of lamps
  • Can be deployed in any shape (circle, linear line, around corners/bends, etc.)
  • Exceeds I.T.E and MUTCD (section 6F.83) specifications.
  • Powered by 4 alkaline D-Cell batteries. ~4-5 months continuous-flash battery life.
  • Operational in any weather; rain, snow, fog, sleet. Unlike lamps that use infra-red communication, weather will not attenuate the radio signal.
  • Improved case design allows for batteries to be dropped in from top, allowing for the lamps to remain bolted when changing batteries. Less time on the highway or in shop. Improved safety and enhanced savings!
  • Longest battery life on the market; 4 to 5 months continuous flashing (depending upon pattern and lens choice)!
  • Lens rotates 90 degrees with novel O-ring bushings. Smooth, friction controlled action provides ease of use while preventing inadvertent rotation by wind or vibration.
  • Nylon inset nut (NyLoc®) where others use standard hex nut. This prevents loosening and tilting (rotation) of lamp during transport and vibration on the truck.
  • Open nylon insert nut to allow for "snugging" of the mounting bolt irrespective of bolt length. Others use "blind" nut hence bolt can bottom thereby preventing tightening.
  • Five flash patterns to choose from. Four sequential patterns, one simultaneous pattern.
  • Battery status check with a push of a button. No need to unnecessarily change batteries! Ask the flare its' battery state.
  • Reverse the sequence direction with a push of a button. Personnel can deploy from either direction - from vehicle towards traffic or the opposite.
  • Easy battery change. No need to unbolt and remove lamp from delineator or barricade. Simply swing open the top and drop new batteries in. Lamp automatically fires back up in proper sequence.
  • Mount sideways (traditional bolt) or lag-bolt down. Only lamp on the market with mounting holes directed downward.

FLASH PATTERNS

Features (Intelligent):

The default pattern: One lamp flashing as it marches down the string. Simple, efficient (battery life ~5 months), effectively guides drivers through a work zone or into a designated parking area. 

From a distance two lamps flashing provide more visibility and guidance. Slightly greater burden on the battery as each lamp is lit twice per cycle. ~3-4 months of continuous flashing. But it sure looks good!

Using Pulse Width Modulation (PWM) we can offer a “tail-off” that provides a more calming effect. Looks smooth and greatly enhances guidance. Uses a bit more energy; ~3 months (or more) of continuous flash time.

Want to get the drivers attention? The Pi-Lit “Fast” pattern emulates the airport runway “rabbit” demanding the drivers eye. They can’t miss it, and this pattern quite effectively slows traffic. You will hear drivers exclaim, “What is that?” as they slow down. Uses the least energy;  ~5-6 months continuous flashing.

More of a tool to designate a barrier or delineator marking the edge of a road way, the simultaneous flash mode can be seen from great distances and paints an edge to the intended path. Battery consumption similar to pattern 3, the “Wave.” Expect ~3 month of continuous flash.

  • Control panel for ease of operation (lockable)
  • Remote Control: Operate and change lamp characteristics from 1,000 feet (300 meters) away
  • Five different sequence patterns to choose from (operator's preference)
  • Five "Group Channels" to choose from. Multiple strings of lamps can be used in close proximity without interference. Can be changed from any one lamp.
  • Lamps will continue to flash in sequence even with a damaged or depleted-battery lamp. System does not get disrupted
  • Insert feature allows a new lamp to replace a damaged lamp without having to turn off entire system
  • Choose between 24-hour mode (flash all day and night) or 12-hour mode (flash when ambient light is diminished)
  • Steady-burn with sequencing; or steady-burn only
  • Bidirectional (front lens only, back lens only, or both)
  • Case design allows lamps to be permanently bolted to a wood post, concrete rail, "Jersey Rail", etc.
  • Standard color cases to choose from: Yellow, Orange, Grey, Blue (Special color available upon request)
