How to map
Add a node at the point where the light source is actually positioned (i.e. next to the way lit).
- ref=* If the street lamps carry numbers intended to help identifying points on the road. For instance, in some places you could call the police and say that there has been a major car-crash on Big Street, southbound at light pole 35, and the police will know precisely where that is. Those identifiers could also be used for reporting broken light bulbs or issuing permissions to hang posters from certain lampposts.
- lamp_ref_swd=* Düsseldorf city only tag for lamp numbers that are not used for navigation, see below.
Consider also using lit=yes on the street or other feature that is illuminated by the street lamp. Unless the lamp is a spotlight or floodlight, it may be unclear exactly where along the street the light diminishes enough that the street would be considered unlit, but the lit=yes segment would at least extend as far as the series of street lamps along the street. lit_by_gaslight=yes is also used in some cities to indicate that a roadway is lit by gaslight specifically.
Note these attributes have not been voted on, but have been used
|support=*||How the light element is placed.
|lamp_mount=*||If support=pole, then
|light:colour=*||Unless a lamp is specifically a decorative light, municipal street lighting will present itself almost exclusively to be either orange (sodium) or white (everything else) and any discolorations are either due to lamp aging, dirt buildup, or variations in chosen color temperature.|
|light:count=*||Number of lights on a pole. (As for LED lamps, the modules are counted, not the individual diodes.)|
|light:lit=*||Time of day that the light is turned on.
|light:tilt=*||-90 for pointing onto the street/pavement, 0 for sideways, 90 for pointing upwards, and anything inbetween|
|light:direction=*||Numerical map direction (0=north, 90=east, etc.) the light points to|
|lamp_model=*||Type or make/model of the lamp (enclosure)|
|light:model=*||Type (make/model) of the “bulb”|
|ref=*||The reference number used by the operator (such as the county council), typically indicated by a sign stuck to the support|
Variations (not currently tagged)
The suspending is commonly done by placing the lamp on top of a pole at the edge of a road or between lanes. Lamps may be mounted on the middle of a roadside power pole instead of a dedicated pole, although the latter may support low voltage power lines (power=minor_line) for electricity supply for the lamps. Another common scheme is to have the poles hold up a suspended carrying wire from which the lamp(s) hang.
In cities, the existing buildings sometimes replace the poles in either scheme. Occasionally, street lamps are attached to other structures of convenient height, such as bridges or road signs.
The mechanism and procedures for turning off and on street lamps vary a lot. Common schemes include turning them on/off at fixed times using a clock, turning them on/off a fixed interval from sunset/sunrise using a more complex clock, turning them on based on a light sensor (which tends to also turn them on in some weather conditions) and turning them off again late at night when there is less traffic. Some schemes also involve only turning on every second street lamp some of the time.

Some cities have unique street lighting systems. See their respective pages for local tagging suggestions:
- Cincinnati (traffic island lights or turtle lamps)
Currently there is a project to map all gaslighted streets and all gaslight lanterns in the town of Düsseldorf. See: Düsseldorf/Projekte/Gaslaternen
(Many of these tags may also be applicable to electrical lamps, though no general scheme has been defined)
- highway=street_lamp Just as other streetlamps
- lamp_type=gaslight Show that the energy comes from gas.
- lamp_operator=Stadtwerke Düsseldorf All streetlamps in Düsseldorf are operated by this organisation.
- lamp_ref_swd=* The number on the lamp mast, given by the operator (SWD).
- lamp_model:de=* In Düsseldorf there are 5 different types of gas lamps in use.
- lamp_flames=* Number of flames in a lamp. There are four, six, eight or nine flames in a gas latern.
- lamp_mount=* Is the lamp mounted on a mast or on a wall?
Possible tagging mistakes
- tower:type=lighting - Poles for lighting, flood lighting columns
- Proposed features/lamp (abandoned) - more flexible tagging of lamps, including street lamps
- Proposed features/Key:light source - new tagging for light sources including street lamps
- operator=*: "If the vast majority of a certain object in an area is operated by a certain organization and only very few by others then it may be sufficient to only tag the exceptions."
