  "textContent": "A night vision system 10 for a vehicle includes a pulsed light source 14 for illuminating a region proximate the vehicle and a secondary trigger light source 21 operating at a predetermined pulse timing and second wavelength. A light sensor 19 detects light at the second wavelength. The trigger light pulses are used to indicate the pulse timing of the primary light source of each vehicle. Upon detecting the trigger light of another vehicle a controller 11 adjusts the pulse phase of the first light source 14 to be exactly out-of-phase with that of the oncoming vehicle. Each vehicle can then adjust its primary light source 14 to be out-of-phase with the other vehicle and hence be non-interfering.",
