To use the lights you need to buy and place 2 AAA batteries per LED light first (4 batteries in total). Open the housing with a screwdriver and release the cover of the housing by placing a coin between the 2 housing parts to separate them. This may require some force. Place the batteries as indicated and click the cover back on. Place back the screws and press the on/off button at the back of the housing to turn on the lights.
