Is it safe for the chairs to be operated in the dark?

Yes, both our X40 mobility chair and E40/E60 series lightweight motorized wheelchair models have rear lights for great visibility in the dark. Our E40 indoor electric wheelchair /E60 outdoor foldable electric wheelchair series also comes standard with a light-touch LED flashlight on the armrest, and our X40 folding lightweight mobility scooter has an armrest flashlight accessory available.
