300mm traffic signal series offer a wide range of modules and pedestrian traffic lights, as well as complete sets of traffic lights. LED light modules come either with transparent, cobweb, or (Fresnel) lens "small" that guarantees an anti-ghost. LEDs have over 80,000 hours of work, they are energy efficient and ensure high visibility due to improved intensity factor light.

Complete sets of traffic lights have a property of highly resistant polycarbonate having characteristic resistance to ultraviolet light. All models comply with CE, RoHS, ISO9001: 2008, and EN12368 standards.

Traffic Light Countdown Timer FAQS:
QWhat is the probable failures if countdown no works ?
Countdown type (software) is not matched with traffic controller type

Driver problem (no input or output )

Control board problem (no signal output)

Need a longer time for learning

Other situations

What should be pay attention when choose the countdown ?
Very important is that what kind of traffic controller will be connected to fixed time type, triggering type, or communicative type.

Features and Advantages:
Application – junction traffic signal counting

Available in learning triggered or communicative version

Ability to be synchronized with any traffic signal controller

Wide operating voltage adapting to different countries

Transparent poly-carbonate optical lens – impact resistant

High intensity LED light source – low energy consumption

Long life cycle – more than 80,000 working hours

Highly durable UV-light resistant polycarbonate housing

Fixation system with L-shaped/arm-shaped mounting brackets
