Sinowatcher is dedicated to save energy worldwide and thus save costs by offering a series of energy-saving and efficient LED traffic lights and road saftety products with first-rate quality yet affordable prices.We also provide racing traffic light, crossing traffic lights, audible pedestrian signal, stop go light, traffic control signals, pedestrian safety lights, city traffic solutions, traffic control solutions, road safety traffic lights, led traffic signal lights and solar road studs.We also provide lane control signals, miniature stop light, in ground traffic lights and so on.

We are glad to announce we have developed new version of our high-power LED light modules. This traffic signal – 200mm sized – is being applied commonly at junctions and provides traffic signaling. As you can see from the table below we replaced 6 LEDs with 3 high-flux surface mount type LEDs which are supplied by Nichia, Japan. They deliver higher light intensity while keeping low wattage. This type of LEDs will provide higher intensity and thus better performance at traffic lighting applications. Furthermore, it is energy efficient traffic light as the light modules consume no more 9W for green, and 7W for yellow and red.
