An HID single light emitting point lamp tube switching device is provided for switching the lamp tube between a far light position and a near light position. Initially, a strong current coil and a weak current coil are induced at the same time, so that the HID single light emitting point are moved to the second position, and at end of a time period set in the timer, the strong current coil will be interrupted so that only the weak current coil is actuated to maintain the HID single light emitting point in the second position.
