Why does the van only have one reverse light?

Why do many of our vans only have one reverse light?

As most of our vans are European, the legal requirements that apply to manufacturers when building a vehicle are different. In Europe, legislation requires only one reverse light to be installed. Many European manufacturers will follow this mandate and only install one reverse light and one fog light, which you'll notice on opposing sides at the rear of many Orange Sky vans.  

The reverse light on the vehicle should turn on automatically each time you put the vehicle in reverse, to let people behind you know that you are backing up.
