PURPOSE: A lamp state displayer of a vehicle is provided to enable a driver to decide the abnormality or replacement time of a lamp in advance or thereafter by installing a displayer for informing a dash board of a lamp state. CONSTITUTION: A life span of a vehicle lamp(1) is finished or the lamp(1) is turned off by a shock so that a current is not supplied to a power circuit. In addition, an electromagnet loses a magnetic force. A display circuit is connected while a spring switch(12) is returned to its original state by a restorative force. Accordingly, the current flows in the display circuit by the contact of the spring switch. Further, a warning light(14) installed on a dash board of a vehicle is turned on and the short state of the lamp is informed to a driver.
