The warning effect of 6' is not inhibited.

Furthermore, since the support frame 33 is interposed between the front surface of the cover 37 and the electric heater sheet 45, an appropriate gap is created between the two. Therefore, the heat from the electric heater sheet 45 is transferred to the cover 27.
This prevents heat from being dissipated through the
This has the effect of eliminating heat loss of the electric heater sheet 45.

(G. Effect of the invention) As is clear from the above description, the vehicle-mounted warning light of the present invention includes a glove in which a warning unit is housed, a sound generator, and a large number of sound-transmitting holes covering the sound generator. It is characterized by comprising a cover and a frame removably attached to the front surface of the cover, and supporting a flexible electric heater sheet in which a large number of sound-transmitting holes are formed in the frame. .

Therefore, in the vehicle-mounted warning light of the present invention, snow falls on the electric heater sheet without blocking the sound transmission hole provided in the cover, and the snow is absorbed by the electric heater sheet. As a result, the path of the sound from the sound generator to the front is not obstructed by the snow, so the warning effect of the sound from the sound generator is not impaired. Furthermore, since the electric heater sheet is supported by the frame body which is detachably attached to the front surface of the cover, the work of attaching and detaching the heater becomes easy. Therefore, it is easy to install the heater only during the snowy season and remove it during other seasons.
