Abstract:
An indicating instrument for a vehicle having a battery and an ignition switch comprising:a dial plate having an indicating gauge disposed on a front surface thereof;a battery-powered high-voltage generator, connected to said battery through said ignition switch, for generating AC voltage much higher than a hundred volt at a frequency more than ten kilohertz;a terminal unit having a pair of high-voltage terminal plates and a plurality of low-voltage terminal plates including terminal plates respectively connected to said ignition switch and an input terminal of said high voltage generator; anda cold cathode fluorescent lamp which is driven by said high-voltage generator through said pair of high-voltage terminal plates and is disposed at the back of said dial plate for illuminating said dial plate;wherein each of said pair of high-voltage terminal plates is spaced apart from the other and from said low voltage terminal plates by an interval much longer than an interval between two of said low voltage terminal plates.
