Zusammenfassung:	Introduced is a method for predicting the remaining life of a lamp, which includes: a current drawing step where a current drawing unit draws a lamp current value which is a current applied to the lamp; a storing step of storing the drawn lamp current value in a memory unit; a change rate drawing step where a vehicle control unit draws a current change rate by using the lamp current value stored in the memory unit; and a remaining lamp life drawing step where the vehicle control unit draws the remaining life of the lamp by using the current change rate. Accordingly, the present invention can replace the lamp before the disconnection of the lamp by previously predicting the life reduction of the lamp. 전류도출부에서 램프에 인가되는 전류인 램프전류값을 도출하는 전류도출단계; 도출한 램프전류값을 메모리부에 저장하는 저장단계; 차량제어부에서 메모리부에 저장된 램프전류값을 이용하여 전류변화율을 도출하는 변화율도출단계; 및 차량제어부에서 전류변화율을 이용하여 램프의 잔존수명을 도출하는 램프잔존수명도출단계;를 포함하는 램프 잔존수명 예측 방법이 소개된다.
