PROBLEM TO BE SOLVED: To grasp wind velocity and wind direction at the same time even at nighttime, in a bad weather, or in the darkness by measuring wind velocity and making a streamer itself lighted in different colors in accordance with the measured wind velocity, and by a driver, etc., visually confirming a difference in the lighted color of the streamer.SOLUTION: Provided is a light emission type streamer in which the streamer itself emits light in order to inform wind direction and wind velocity, the streamer comprising a suction port 2 having a circle 5 attached at one end, a streamer body 4 having a blowoff port 3 at the other end, a pole 6 for hooking the suction port 2 side of the streamer body 4, a wind velocity measurement device 9 for measuring wind velocity, and a light source 12 for making the streamer body 4 lighted in different colors, the streamer being configured so that the streamer body 4 is made to emit light in different colors in accordance with a difference in the wind velocity measured by the wind velocity measurement device 9.SELECTED DRAWING: Figure 1 |
