Three battery operated push lights (Rudgwick RH12)

3 white push lights. Diameter 14cm. Press surface to turn on and off. Two have been used and gone a bit yellow. One still in wrapping and still white. Been in a cupboard for many years. Each takes 4 AA batteries. They have a hole on the back to hang on a screw (screws and batteries not included).
Useful for sheds, power cuts, or anywhere without a mains supply, though probably not outdoors!
