Indicates whether a feature is lit.
The key lit=* indicates the presence of lighting. Most often used on a way tagged with highway=* but sensible on many other ways, too.
- lit=24/7: Both night and day; e.g. in tunnels.
- lit=yes: At night (unknown time schedule or daylight detection)
- lit=automatic: When someone enters the way the lights are turned on.
- lit=no: There are no lights installed
- lit=operating times: Use the schema of opening_hours to document when the light is ON, when the lighting is solely or primarily time dependent. For example lit=Mo-Fr 05:00-07:45 for a way lit for working days' morning rush hour only.
- lit_by_gaslight=yes: For streets lit by gas lighting.
lit=* can be used on nodes, ways, areas or relations.

How to tag a tunnel where lamps are installed but they are never turned on because the city wants to save money?
- I recommend to tag that lit=no. (?)
- I recommend to tag that lit=disused. (--Plasmon 09:50, 5 July 2009 (UTC))
- I recommend to tag that lit=disused. --Bahnpirat 14:20, 30 October 2009 (UTC)
- I recommend to tag that lit=disused, because existing poles are means of orientation for blind persons. --Lulu-Ann 13:49, 12 April 2011 (BST)
Should this be used to tag individual light columns? Rationale being that we could then ease the reporting of failed street lights to the respective councils if we collected their positions whilst surveying - after all, there tend to be less street lights than house numbers, which we're encouraged to collect...
