Abstract: A device for detecting the solar radiation quantity of the sunlight coming in the passenger compartment of an automobile is construct to correct a solar radiation quantity by adding an amount of correction to the solar radiation quantity obtained based on the composite of plural detected values from a solar radiation sensor when the direction of the sunlight is deviated from the direction of travel of the automobile beyond a prescribed range, whereby the solar radiation quantity used for the control of an automobile air-conditioner is prevented from being lowered in case of deviated solar radiation. The solar radiation quantity coming into a rear portion of the passenger compartment is detected and compared with the front solar radiation quantity. A larger one of the front and rear solar radiation quantities is used as a solar radiation quantity for the control of the automobile air-conditioner to cope with the solar radiation coming from every direction relative to the direction of travel of the automobile.

Abstract: A brake lamp apparatus causes a neon discharge lamp to light up instantly even when the vehicle key is not inserted into the key hole of the vehicle e.g., when the vehicle is being parked. A neon discharge lamp utilized in the apparatus is pre-heated but cathodes thereof to instantly light up in hot cathode discharge mode upon depression of a brake pedal when a generator drivingly connected with an engine is operating, whereas the hot cathodes of the lamp are not pre-heated but the lamp can still light up instantly in cold cathode discharge mode upon depression of the brake pedal when the generator is operating. Even if the filament coils of the lamp become cut off suddenly while the vehicle is running, the lamp can still light up, being shifted to in cold cathode discharge method, thereby overcoming a drawback that the brake lamp goes off suddenly due to a filament cut-off during running on a road.
