## Abstract

A direction indicator for vehicles, having a first lighting unit containing a first light source and an optical unit paired with the first light source for generating a direction indicating function and comprising a second lighting unit containing a second light source and an optical unit paired with the second light source for generating an additional lighting function. The first light source and the second light source are paired with the same optical unit, and the second lighting unit is designed as a light-emitting visual information lighting device. The second light source can be activated and/or deactivated depending on a vehicle signal which triggers a non-lighting function of the vehicle.

## Claims

### Claim 1

A side-mounted direction indicator for vehicles comprising:
a first lighting unit having a first light source for generating a side-mounted direction indicating function;
a second lighting unit having a second light source for generating an additional lighting function; and
an optical unit associated with and assigned to both of the first light source and the second light source, such that the optical unit is a same optical unit shared by the first light source and the second light source,
wherein the first light source and the second light source are arranged on a common carrier,
wherein the second lighting unit is configured as a visual light-emitting informational lighting device, and
wherein the second light source is adapted to be switched on or switched off as a function of a signal of the vehicle that triggers a non-lighting function of the vehicle.

### Claim 2 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein the second light source is controlled such that the second light source is switched on or off when sending a signal which activates the unlocking of a vehicle door and a signal which acts on a door closing device of the vehicle, and/or when sending a signal which activates the locking of the vehicle door.

### Claim 3 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein the carrier extends in a direction of extension of the side-mounted direction indicator, wherein, along the carrier, a plurality of first light sources and a plurality of second light sources are arranged from which light is emitted via the optical unit in the direction of a lens closing off a housing of the side-mounted direction indicator, and wherein the second light sources radiate light of such a light color that the second lighting unit is adapted to be used for generating an informational lighting function for a user of the vehicle.

### Claim 4 (depends on 3)

The side-mounted direction indicator according to claim 3, wherein the first light sources and the second light sources are arranged in pairs at a small distance from one another.

### Claim 5 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein the side-mounted direction indicator is integrated in a lower housing section of an outside rearview mirror and is bounded by an upper housing section, and wherein the lower and upper housing sections of the outside rearview mirror accommodate a mirror arrangement.

### Claim 6 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein the optical unit is formed by an elongated rod-shaped or flat-shaped optical fiber, on one front end of which the first light source and the second light source are arranged and which has dispersedly arranged outcoupling elements so that coupled-in light is laterally deflected or decoupled.

### Claim 7 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein the first light source emits light of a yellow light color and the second light source emits light of a light color which differs from the yellow light color of the first light source.

### Claim 8 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein the second light source is embodied as an RGB light source, or wherein only a single RGB light source is provided as the light source for generating the side-mounted direction indicating function with a yellow light and for generating the informational lighting function with another light color.

### Claim 9 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein the side-mounted direction indicator is integrally arranged in a decorative trim strip or on a lateral edge of the vehicle.

### Claim 10 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein the optical unit is a reflector.

### Claim 11 (depends on 1)

The side-mounted direction indicator according to claim 1, wherein a plurality of the first light source and a plurality of the second light source are provided, wherein the plurality of the first light source and the plurality of the second light source are arranged in pairs that extend along a length of the carrier in an extension direction thereof, each pair including one of the first light source and one of the second light source, such that whether light is emitted from the plurality of the first light source or from the plurality of the second light source, the light is uniformly distributed along the length of the carrier in the extension direction thereof.

### Claim 12 (depends on 11)

The side-mounted direction indicator according to claim 11, wherein a distance between the first light source and the second light source within each pair is smaller than a distance between adjacent pairs.
