Disclosed is an inner lens provided in a lamp, the inner lens including a light transmission part through which at least a portion of a light beam output from a light source passes and is then output, a light distribution formation part that outputs, to an outside of the lamp, a light beam, which forms a light distribution pattern, within a transmission light beam that is the light beam output from the light transmission part, and an image formation part that outputs, to the outside, a light beam, which forms an image pattern, among the transmission light beam.

A light guide element including at least one light guide unit, each light guide unit having at least one first light entry part, at least one first reflecting part, a second reflecting part and a first light exit part. The second reflecting part and the first light exit part are disposed in a peripheral region of the light guide unit. The first light entry part receives light rays from a light source; the first reflecting part reflects light rays from the first light entry part towards the second reflecting part in the peripheral region. The second reflecting part reflects light rays from the first reflecting part towards the first light exit part, such that the light rays emerge from the first light exit part. A lighting device and a vehicle may implement the light guide.

A second light unit has a light source and a second flat light guide having a linear light coupling surface and a linear light decoupling surface. The first flat light guide and the second flat light guide are connected to each other in a single piece to form a light guide element. Opposite flat sides of the first light guide and opposite flat sides of the second light guide intersect in an intersection area. The first flat light guide has a deflection section between a first flat section and a second flat section of the first flat light guide. The first flat light guide and the second flat light guide form a U-shaped light guide element in a transverse plane.

A running light for a vehicle includes at least one light source, a number of first optical waveguides on a first side, a number of second optical waveguides on a second side opposite the first side. One of the first waveguides emits light from the at least one light source in both the main beam direction, which runs along a main axis orthogonal to a secondary axis connecting the first side and second side, as well as in a first area toward the number of second waveguides. The second waveguide emits the light from the at least one light source in both the main beam direction and in a second area toward the number of first waveguides.
