In daily traffic trips, we often encounter low-visibility weather conditions such as rain and fog at night, and it will be found that the signal light poles are not eye-catching enough, which may easily cause traffic accidents and pose a traffic safety hazard. Therefore, in many cities, traffic police departments have begun to uniformly paste yellow reflective film on traffic signal light poles.

Under normal circumstances, the exterior of traffic signal light poles is galvanized, and the exterior color is gray or silver gray, which plays a role of anti-corrosion and rust prevention. However, gray or silver gray signal light poles are not eye-catching enough in low-visibility weather conditions such as rain and fog at night, which may easily induce traffic accidents. After careful investigation, experts in the traffic field suggest that yellow reflective film should be attached to traffic signal light poles at intersections. The reflective film should be a high-quality secondary or first-level film, that is, the main body of the signal light pole remains unchanged in gray or silver gray, and the reflective film should be pasted at an interval of 50 cm. .

According to reports, the yellow reflective film has high visibility and is more eye-catching at night and under low-visibility weather conditions. It can serve as a warning to vehicle drivers and remind drivers that they have entered an intersection and should drive cautiously in accordance with the instructions of traffic lights. At the same time, it also plays a certain role in beautifying and protecting the signal light pole.

At present, you can see the test points of yellow reflective film at intersections in many areas such as Qingdao and Weifang. After further optimization, it will be promoted at intersections of signal lights in other urban areas.
