## {% linkable_title Calling Services %}
The following example shows how to call a service from `python_script`. This script takes two parameters: `entity_id` (required), `rgb_color` (optional) and calls `light.turn_on` service by setting the brightness value to `255`.
```python
entity_id = data.get('entity_id')
rgb_color = data.get('rgb_color', [255, 255, 255])
if entity_id is not None:
service_data = {'entity_id': entity_id, 'rgb_color': rgb_color, 'brightness': 255 }
hass.services.call('light', 'turn_on', service_data, False)
```
The above `python_script` can be called using the following JSON as an input.
```json
{"entity_id": "light.bedroom", "rgb_color": [255, 0, 0] }
```
