Solar garden lights are a great way to light your garden in the evening and night while not using any electricity. They use a battery that collects power from the sun during the day and converts it into energy for the battery to run on the evening. There is a also a solar light bulb in the garden lights that is usually low-voltage, and it is connected to the battery and collects its energy to run from it. Once a year you have to change your solar garden lights' batteries and light bulbs so they keep working well.
Purchase a new solar bulb and solar battery that is compatible with your solar garden lights. Hardware stores will carry solar garden bulbs and batteries.
Unscrew the top of the solar light with the screwdriver or pop it off with your hands if it does not have a screw in it.
Remove the solar battery and bulb from the solar garden light. Unsnap the battery from the wires and pull it out. Unscrew the solar light bulb from its connector.
Connect the new battery to the solar garden light. Take the wires that are connected to the solar garden light (they should be red) and plug them into the bottom of the solar battery. The plug should look similar to a 9-volt battery. Place the solar battery into the solar light container behind the bulb. Screw the new solar light bulb in place.
Snap or screw the top of the solar garden light back on.
