The utility model relates to a night vision device for automobiles, which can promote safe operation. The night vision device comprises a far-light lamp bulb (11) for irradiating visual light and infrared, a near-light lamp bulb (12) for irradiating visual light, a rising display (30) for displaying images shot by a night vision video camera, and a light filter (13) for shielding visual light, wherein the light filter can be shifted to a first position covering the far-light lamp bulb (11) and a second position leaving the far-light lamp bulb (11). When a starting switch (51) of the night vision device is switched on, both of the lamp bulbs (11, 12) are illumined; the light filter (13) moves towards the first position; the rising display (30) acts and displays the images. When the light filter (13) is positioned in the second position and the near-light lamp bulb (12) is extinguished, the light filter (13) is also forbidden to move from the second position to the first position even if the starting switch (51) of the night vision device is switched on.
