## Abstract

A projection headlight for a vehicle is provided comprising at least one light source, a projection lens, a condenser lens arranged between the at least one light source and the projection lens, and at least one printed graphic arranged between the condenser lens and the projection lens. The condenser lens has a flat side and a curved side. The at least one printed graphic is printed on the flat side of the condenser lens. Further, a vehicle is provided having at least one such projection headlight.

## Claims

### Claim 1

A projection headlight for a vehicle, the projection headlight comprising:
at least one light source,
a projection lens,
a condenser lens arranged between the at least one light source and the projection lens, the condenser lens having a flat side and a curved side, and
at least one printed graphic arranged between the condenser lens and the projection lens, wherein the at least one printed graphic is printed on the flat side of the condenser lens.

### Claim 2 (depends on 1)

The projection headlight according to claim 1, wherein a collimator is arranged in front of each light source.

### Claim 3 (depends on 1)
