It's been pretty dark during my morning walks and depending upon how late I'm out in the evenings, it can turn dark quickly. So my peeps have put little lights on the back of my wheelchair so that people and cars can see me.
There's a white flashing light on my left side and a flashing red one on my right.
I feel safer with them on. When they're flashing, they kind of look like Christmas lights and people smile. And that's a good thing.
