An illumination arrangement for a vehicle headlight is formed of a plurality of contiguous elementary cells, each including a light source, defined by an emission surface having a horizontal dimension and a vertical dimension and capable of emitting a luminous flux, and an optical system capable of conveying the luminous flux at a predetermined solid angle about a predetermined direction. The elementary cells are disposed so as to generate overall a predetermined distribution of light emission. The horizontal dimension and the vertical dimension of the emission surface of the light sources are different. The vertical dimension is less than 1 mm and the ratio between the horizontal dimension and the vertical dimension is greater than 2.
