TNL-25
LED flash unit for ITS applications
JAI’s compact TNL-25 flash unit offers high-performance LED lighting at a size and price perfectly suited to slow speed or side-fire installations. Its array of 25-LEDs delivers a bright yet diffuse lighting pattern designed for close-in geometries.
Off-angle illumination for better enforcement
The TNL-25 is designed to complement on-axis ring lighting used to illuminate number plates in dark conditions. Its bright, yet diffuse illumination makes sure that the entire vehicle and surrounding details are also properly exposed for a more complete and indisputable enforcement package.
Small size perfect for side-fire applications
At only 4-1/4 inches wide and less than 6 inches high, this compact unit mounts easily on poles, walls, or other structures to provide side-fire lighting for stationary, slow-speed, or other close-in geometries.
Multiple spectral options
With wavelength options including NIR (850nm), blue (470nm), and white (visible spectrum), the TNL-25 can be configured to support the highest possible automated read rates regardless of time-of-day or number plate color schemes.

Here are a few applications where TNL-25 systems are especially suitable
TNL-25 LED flash systems can be configured for a variety of ITS applications.
Toll collection and violation enforcement
At traditional toll booths, TNL-25 complements LED ring lighting to provide the off-axis illumination needed to ensure proper exposure of vehicles in all lighting conditions.
Border and access control
TNL-25 provides reliable 24/7 operation for monitoring border crossings or for vehicle identification prior to granting access to restricted facilities.
Weigh-in-motion systems
For integrators implementing weigh-in-motion systems, TNL-25 ensures that reliable plate and vehicle images of large vehicles can be captured day or night at normal traffic speeds to maximize the efficiency of transport.
Congestion charging
TNL-25 can help capture plate and vehicle images of road users who congest specific areas and/or times to support initiatives that encourage smarter driving habits and the use of public transportation.
Parking Lots
Low power, lower cost configuration makes the TNL-25 well-suited to parking lot scenarios or other applications involving stopped vehicles and/or shorter lighting distances.
