摘要： 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.
