The key light_source=* is used to map a light emitting object. It is more generic than highway=street_lamp.
Values
Typical values could be:
| Value | Comment | Photo |
|---|---|---|
| lantern | A lantern is a light source whose purpose is to illuminate broad areas. Typical examples are street lights, but the term “lantern” is more generic and also applies to light sources which illuminate other areas than highways. |
|
| floodlight | A floodlight is a broad-beamed, high intensity artificial light typically used at sports events or music stages. | 
|
| aviation | Used in aviation for, e.g., runway lighting. | 
|
| warning | Marks the position of hazardous spots, such as wind energy towers, high buildings etc. | 
|
| signal_lamp | A signal lamp is used to convey information / communicate by encoded light signals, e.g., morse code. Not to be confused with a traffic signal, railway signal etc.! |

Additional tags
- support=* – Type of support/mount or positioning for the light source.
- light:method=* – Which light generation method/technology is used (values as for lamp_type=*, e.g electric, led, fluorescent).
- light:colour=* – Colour of the emitted light, e.g. 5000 K, white, orange, 560 nm.
- light:lit=* – Time of day the light is turned on or method by which it is turned on (values as for lit=*, e.g. 24/7, dusk-dawn, 20:00-08:00, automatic).
- light:tilt=* – Angle of inclination of a directed light source. Use -90 for pointing onto the street, 0 for pointing sideways, 90 for pointing upwards, and anything in between.
- light:direction=* – In which (map) direction does a directed light source emit most of its light? Use an angle or a cardinal direction as a value (e.g. 45, 270, NE, W).
- light:shape=* – What kind of shape does the light source have? This determines the way the light is distributed. Typical values are:
- cylindrical – The light is emitted around a rotation axis.
- directed – The light is emitted mostly in one direction.
- spherical – The light is emitted in all directions.
- cylindrical – The light is emitted around a rotation axis.
- light:count=* – How many light sources are there (on a lamp pole, for example)? The default value is 1. With LED lamps: do not count the individual diodes!
- operator=* – The operator of a light source.
- manufacturer=* – The manufacturer of a light source.
- model=* – The model name / model number of a light source.
- ref=* – If the light source has a reference number.
