Because it deteriorates with ultraviolet rays, it has to be replaced regularly, but it is saved because there is no treatment of the cover alone at the home center. Also, since the price is affordable, I also purchased spare parts
I did not know the existence of this indicator cover, but since I saw the catalog and the price was also cheap, I bought it. Since this cover is deteriorated by ultraviolet rays and rain and the transparent part becomes cloudy, it feels good after replacing. Installation was also easy.
