LR-15 L Solar Radar-Activated Rapid Flashing Beacons

New product

We’ve combined the functionality of a traditional speed display and flashing LED speed limit sign to create an effective tool that brings driver attention to the posted speed limit when needed.

More info

The radar is configured to activate flashing beacons when the measured vehicle speed exceeds the preprogrammed threshold to brings driver attention to the speed limit sign. LR-15L remains almost invisible in standby mode reducing driver’s habituation and light pollution


  • High-accuracy Doppler radar measures the speed of each vehicle and capable to track multiple vehicles moving in both directions at the same time.
  • Virtually unlimited data storage on a removable Micro SD card allows continuous recording of 10+ years of detailed traffic statics. All information is stored in MS Excel compatible files (CSV).
  • Onboard graphics OLED display and keyboard allows to set all important parameters of the system and verify proper positioning and functioning of the radar.
  • No software required to set up the system or collect traffic data from the device.
  • Integrated Solar MPPT charger and advanced power management system ensures long autonomy.

LR-15L has proven to be an effective traffic calming tool:

  • Over 30% of drivers responded to strobes and slowed down.
  • The number of serious speeding accidents was reduced by more than 40%.
  • The average speed was reduced by more than 6 km/h.
  • 85th percentile speed dropped by more than 10%.

LR-15L collects inbound and optionally outbound traffic:

  •   Time-stamped records for each target with up to a second resolution.
  •   The Average, Minimal and Maximal speed of each vehicle.
  •   Vehicles size estimation.
  •   Speed variation (acceleration or deceleration).
  •   Programmable Speed Bins summary.

Advantages and Benefits

Wide road with a dense traffic pattern

Typically, a Radar Feedback Sign is not capable to make a difference between multiple vehicles that are traveling close one to another. The LR-15 can help eliminate the confusion. It will activate in cases if at least one vehicle in a group moving faster than the programmed speed threshold.

Limited real estate on a pole

It happens very often – multiple signposted on the same pole. As a result, there is no space to install a Radar feedback sign without obstructing other important information.  Thanks to extremely low profile and small footprint, the LR-15 can help in this situation.

Telespar or U-channel signpost

Commonly used light signpost is not capable to support the weight of a full-sized radar feedback signs. At the same time, the installation of a stronger wooden or steel post may not be an option. In this case, you may consider using LR-15 as an efficient alternative to a Radar Feedback Sign.

Need for effective traffic calming measures on a small budget?

The LR-15 is the most affordable non-intrusive traffic calming measure on the market. It costs considerably less than a typical radar feedback sign including the installation cost.

LR-15L weel make a SPEED LIMIT sign visible when it is needed!

Speed Limit Signs - Unintentional Violation

Drivers are unaware of the speed limit and consistently underestimate their speed. A person can miss a speed limit sign or may not remember the last passed sign.

Variable Speed Limit (VSL) and driver’s habituation

Study shows - most drivers had failed to notice the speed limit change (58.3%) and 6.25% still to be unaware that the speed limit changed after passing all consecutive signs.

Work Zones

Of those drivers who stated that they knew the temporary Speed Limit, 76% identified the speed limit correctly. The limited sight distance in work zones increases the possibility that a driver may be unable to see the temporary speed limit.
