So street lights that shed their leaves in the winter? Or that die during a drought? Relying on the variable metabolism of trees to prevent car crashes doesn't sound like a good idea. Something like large columnar tanks filled with cyanobacteria or algae, that can be recolonized quickly when thrown out of equilibrium, would make more sense.

Even if you used conifers to keep them going year-round, they don't seem like very good street lights. I want a few to use as nightlights. Even if the first plants are fairly dim, if there's not a lot of competing light they could be reasonably effective.
