This poster advertising Philips H4 (Halogen) Allweather headlight bulbs is based on a photograph of an owl, a creature known for its exceptional night vision, against a night sky illuminated by a pair of the bulbs. In recent decades, European companies like Philips, Bosch, and Osram have released similar posters reflecting the intense competition between them as they seek to develop the latest in LED and other bulbs used for car headlights.
