As you will pass through Roche Bois, on the motorway, you will notice two yellow led lights blinking on both sides of the road.
If you take a closer look, you might notice that this light is powered by a solar panel. Well it is a good step to take in such an area but it was only after a few incidents occurred, This should have been done on the first day the cross-here was operational.
I also like the idea of using a solar panel to operate this warning light. I still do not know whether it also operates at night.
Anyway, better late than never. Hopefully drivers will be more careful now.
