SAN DIEGO - Petty Officer 1st Class James Coleman and Petty Officer 3rd Class Jason Flores, members of U.S. Coast Guard Aids to Navigation Team San Diego, verify that the newly installed light-emitting diode beacon operates correctly at the Point Loma lighthouse in San Diego, Feb. 6, 2013. The LED system is brighter, uses 96 percent less energy and requires less maintenance than the incandescent lantern it replaced. U.S. Coast Guard photo by Petty Officer 1st Class Henry G. Dunphy.
