Teknoware has implemented in Finland the interior lighting in 40 Helsinki Artic generation trams using LEDs. Each car will be lighted with two direct and two indirect lines of lights. Special attention has been paid to energy efficiency in the lighting, which is achieved through an active dimming function, where a control unit adjusts the brightness of the vehicle's interior lighting by means of sensors according to external lighting conditions. Driver safety is increased by LED spotlights that turn on and off gradually in order to prevent glare. The rear car's outer arc is accentuated with curved, interior LED lights.
The first test run of the new Artic tram models with low floors for easy access was made in August 2013. Lighting deliveries have begun in 2015 and will end in 2018.
