## Abstract

Lighting control systems and methods for providing dynamic control of multiple light sources with a single input are disclosed herein. When a long touch is detected at a user interface element, a first light source is turned on. If the long touch persists for a predefined time period, a second light source (e.g., an adjacent light source) is also turned on. The luminosity of the first light source may be gradually increased from zero to 100% during the predefined time period. If the long touch persists beyond the predefined time period, the luminosity of the second light source may be gradually increased from zero until the long touch ends or a second longer predefined time period is reached.

## Claims

### Claim at position 1

1-20. (canceled)

### Claim 21

A system comprising:
a light source; and
control circuitry configured to:
in response to a first touch detected on the light source, activate the light source;
in response to a second touch detected on the light source, decrease a light level of the light source; and
in response to a third touch detected on the light source, deactivate the light source.

### Claim 22 (depends on 21)

The system of claim 21, wherein the light source is located on a vehicle.

### Claim 23 (depends on 21)

The system of claim 21, wherein the light source is located on a ceiling of a vehicle.

### Claim 24 (depends on 21)
