Led traffic light is used on the intersection or other special site,used for indicating the driver and the pedestrian’s action. From the definition, we can see traffic lights quality and people's lives, travel are closely related, and safety issues related to drivers and pedestrians. So the LED traffic light quality is the most important factor for judging on whether the project good or not.

First , need assess traffic light factory qualifications.

In china, Traffic lights manufacturer concentrated in Guangdong, Jiangsu, Zhejiang, Shandong and Jiangxi area, truly qualified and scale manufacturers not more than 30. So, buy traffic lights, we can begin to look for from these places. In regard to quality, the ranking should be in front of factory in Shenzhen, especially while doing exit lighting manufacturers.

After find the factory, you should check the company information,such as whether the factory is special in led traffic light. Whether they have international test report. Whether they have export to your local city.

2. Second, need to know the quality and price

When looking at the factory, quality control need be critical, you can take a look at the electrostatic protection, employees are strictly required to wear an antistatic wrist strap, grounding equipment if there is work to do.

Further wave, angle cutter, grounding and inspection of the soldering iron should concern because of the machinery, equipment or tools to live a long time, and are prone to leaking, so the usual protection and detection work is important. Ask LED light intensity test equipment, high and low temperature aging equipment, salt spray test equipment, etc situation. Check the led brand hip, the pc housing IP rate, the warranty, the luminance. The watts etc.
