As we all know, there is a unified standard for the naming of the national standard 
Road Stud, so is there any standard for 
Road Stud lights? For a 
road stud lamp that meets the national standard, first check whether its specifications and models meet the national standards.

If the specifications and models do not meet the national standards, the "manufacturer" is definitely lying because they are not familiar with 
Road Stud products. Many small manufacturers, especially workshops, buy a simple PLC programming board to charge the traffic signal control machine, and its release period and phase are single.

The solar multi-period and multi-phase 
Road Stud independently developed by Quanluan Company has an automatic dimming function, and has 32 kinds of release schemes for 99 time periods in a day, with a maximum of 36 outputs, and different release schemes for holidays and working days. Remote control is optional for on-site traffic control, which can meet all intersection traffic 
Road Stud light release requirements.

Here is an example of the naming rules of 
Road Stud lights: YDT31-3/R.Y.G, other YD stands for mobile, T stands for solar charging, 3 stands for signal lights with a diameter of 300mm, and R.Y.G stands for red, yellow and green full screen.
