PROBLEM TO BE SOLVED: To provide a translucent cover with an electrothermal circuit for a traffic light and an indicator that are safe and inexpensive, and can stably exert an excellent snow accretion prevention effect for a long period.SOLUTION: A translucent cover with an electrothermal circuit 1 for a traffic light attached to a traffic light 10 using an LED 14 as a light source is made by stacking a light transmission body layer 2 that lets light pass through at least in the radiation direction of light of the LED and a heating conductor layer 3 in which an electrothermal circuit 3a for resistance heating is arranged at a place where it does not obstruct the light radiated by the LED. It is detachably attached to the traffic light.SELECTED DRAWING: Figure 2
