An illumination device comprising:

• a plurality of light sources;
• a housing in which the plurality of light sources are disposed;
• an input device disposed in the housing and configured to accept a first operation and a second operation different from the first operation;
• and
• a control device configured to execute
• accepting a first input representing a first combination that is a combination of a lighting and blinking pattern and a light emission color of the plurality of light sources in a first mode,
• accepting a second input representing a second combination that is a combination of a lighting and blinking pattern and a light emission color of the plurality of light sources in a second mode and is different from the first combination,
• controlling a brightness of the plurality of light sources when the input device accepts the first operation,
• causing the plurality of light sources to emit light in the first mode, based on the first combination, when the input device accepts the second operation, and
• causing the plurality of light sources to emit light in the second mode, based on the second combination, when the input device accepts the second operation again.
