The Diamond Head Lighthouse, originally built in 1899, spreads light nearly 18 miles out into the Pacific Ocean.
The house's Fresnel lens burns at 60,000 candle power. Perched on the side of the extinct volcano Diamond Head, the lighthouse lays down a red sector to warn vessels to stay away from the reefs at Waikiki.
