IDEC OPTO DEVICE is Keihan Electric Railway Co., Ltd. In order to prevent accidents on streetcars and automobiles, LED display panels (photos) are mounted on the front, rear, and side of the electric body to contribute to the safety of the electric train.
The photo of the tram is 800 systems. It is a special high-tech electric train (Supper High-tech Train) with a special specification and special equipment that runs on the Tozai Line subway in front of Hamadatsu to Kyoto (in front of the Marina Taijin-Kyoto City Hall).
For the purpose of preventing accidents with automobiles, field tests conducted on trams showed that the number of trams equipped with LED display panels was drastically reduced.
Now, all the trams running on the ground section of the Beijing-Tianjin-Hebei line use orange LED display boards as vehicle-wide lights.

In particular, from the train bound for Hamadatsu to Kyoto, you can enjoy a sharp turn in the direction of Mount Biwa while watching the lights of Otsu in the distance. One of the charms of the 800 system is that you can see the smooth orange lights on the left and right, into the mountains, like the trains that drive into space.
