Mazatlán's lighthouse (El Faro) began operating in mid-1879. The maritime signals were manufactured in Paris, France, containing a large oil lamp with mirrors, and a Fresnel lens to focus the light. Since the light was static, from a distance it was often mistaken for a star. By 1905, this lamp was converted to a revolving lamp. During that period, the Mazatlán lighthouse was considered to be the naturally highest in the world. Today, the 1000 watt bulb can be seen for . Near the lighthouse shore, famous "divers" (called this even by the Spanish-speaking inhabitants of Mazatlán) perform daring jumps off high rocks into the Pacific Ocean, for tips from onlooking tourists.
