Easy fix.....Replace the batteries, just make sure they are solar batteries you can find them at Lowe's or Home depot even Wal-Mart
Mary: maybe this will help
Replace the batteries. Make sure they are rechargeable. Clean the solar panel. Batteries usually last about a year.
Hi Mary. They most likely need a new battery. Find where the battery is (you usually have to unscrew a cover. You can find replacement ones at a home improvement store usually by the solar items. Good Luck!
