ALL-SEASON is the name given by OSRAM to its yellow-coated range of headlight lamps. The yellow impression is provided by interference filter coatings that are applied to the bulb in sequence of consecutive operations. This enables an extremely precise and virtually loss-free change to be achieved in the color location (<1% loss of luminous flux).
From certain angles of reflection, Car Light equipped with these lamps also appear bluish. The color location of the ALL-SEASON coating lies within the standardized ECE white field and, in contrast to the selectively yellow-coated "French yellow" lamps and it can be used without restriction in all Car Light. An ALL-SEASON lamp can replace any clear lamp.
