A lighting device providing an improved visibility

A lighting arrangement for outdoor illumination, said lighting arrangement comprising:

• a first light source for emitting a first light, the first light source being arranged in a first lighting device;
• a second light source for emitting a second light, the second light source being arranged in a second lighting device;
• a first modulating optical element for converting said first light into a modulated first light providing a first illumination pattern on a first target surface, and
• a second modulating optical element for converting said second light into a modulated second light providing a second illumination pattern on a second target surface,
• wherein the second lighting device is arranged at a distance from the first lighting device, the distance being from 0.3 m to 10 m,
• wherein said first target surface and said second target surface at least partially overlap,
• wherein each of said first illumination pattern and said second illumination pattern comprises a sequence of alternating illuminance peaks;
• and
• wherein said first illumination pattern is substantially complementary to said second illumination pattern.
