を特徴とする閃絡表示器。 A flash detection circuit includes a light emitting section that generates a detection light based on a flash current flowing through a flash detection object, and a light receiving section that receives the detection light and converts it into a flash detection electrical signal; a display circuit that displays the presence or absence of a flash fault based on a detected electrical signal; a coloring current supply circuit that supplies a coloring current for imparting a color change to the electrochromic display based on a detected electrical signal; and a coloring current supply circuit that corrects the temperature dependence of the coloring density of the electrochromic display to achieve a predetermined coloring. The electro-concentration
and a temperature correction circuit that controls the coloring current supply circuit so that coloring of the chromic display body is stopped, and the coloring current supply circuit uses a solar cell and a rechargeable battery as a power source. A flashlight indicator featuring:
