OpenStreetMap
the number of illuminated streets is rapidly growing:

Do you want to illuminate your street as well?
Just add lit=yes, if there is light (or lit=no, if there is no light)

Any thoughts on whether there should be any implied lit=yes for certain types of highway?
For example, in the UK it is relatively rare for a residential road to be without street lighting, to the extent that the presence to lighting is used to 'regulate' speed limits.

in Belgium, I only know 2 unclassified highways which aren't lit, so you may make Belgium completely lit :P
In any case: every residential, primary, secondary, tertiary, motroway or trunk highway is lit, there are only exceptions on the unclassified higways.

Perhaps you could render highway=street_lamp as point light sources?

(except where lit=no on them)

I add this tag all the time for road paths car parks, I found a few residential roads unlit too

Actually, this is not a rule ererywere in the planet. In many places the lighting is not coincidentall with the "street", so i think it's not a good way of doing it. The lighting should come from some kind of "street-lamp" tag not a tag for the way.
