Two sides provide signage for car / bike and two for pedestrians. Very nice for start explaining signage small, especially the pedestrian part.
There is an on / off button but it is also off by itself after a while. By cons even with new batteries the brightness is not excellent outside. Inside we see the color changes but it is low enough to play outside.
Another positive point, it can be disassembled and returned in a little box.
This is a good product but which loses its usefulness since it becomes difficult to use in the garden if you want to see the changes of lights.
