if you look carefully you can spot the Belgian motorways which were fully lighted until a couple of months ago. Nowadays they're not fully lighted anymore. The lights are still there, but they're not always turned on anymore.
(A lamp post every 50metres)...
Unfortunately Belgian road paint and direction signs are not prepared for this.
Road paint does not reflect in Belgium, nor do they have cat eyes.
Directional signs do not reflect, usually they're lighted from the inside..
