<p>The light source for night vision is integrated with a signaling lamp on the vehicle. The source has a lamp (4) emitting white light which is passed through a filter (10) to emit a mixture of white light and infrared light with wavelengths in the range 800 to 1200 nm. The intensity of white light is less than 2000 Cd, and the intensity of the infrared light is greater than 25 W/sr.</p> |
