The light's focal plane on Gibbs Hill Lighthouse, therefore, is at 354 feet (108 m) above sea level.
Sixty-thousand people ascended the lighthouse in 1985, and it continues to be a popular tourist attraction.
A radar antenna for marine shipping was installed atop the lighthouse in 1987 supported on a steel space frame fixed at the original bolt locations.
The radar and supporting frame were undamaged in September 2003 despite the oscillation of the tower during Hurricane Fabian.
This movement caused 2 imperial gallons (9.1 L; 2.4 US gal) of mercury to slop out of the lens support trough and put the light out of operation.
