Swap out your outdated string of incandescent Christmas lights for energy saving LED ones at Home Depot 10 am. Thursday. Pacific Gas and Electric say customers use 75-percent less energy with LED, emit very little heat and are made with epoxy lenses that are resistant to breakage. The exchange takes place at Home Depot at 8700 on Rosedale Highway. Your old lights will be donated to the Bakersfield Association of Retarded Citizens and recycled.
