LED flashlights have become smaller, brighter, and less expensive. Get her a small LED light for her purse, the glove box in the car, her night-table, or any place else where it would be of use.
Or – get stick up LED lights. We put a couple of these in our closet at our last home, and when we moved them a year later they were still running bright on the two AA batteries we put in each of them to start. LED stick up lights are a fast and good solution for places where you need light and don’t want to run wires.
