Both of the range lights have been replaced with new solar powered LED units. They are extremely bright and are visible anywhere from 5.5 to 8 nautical miles away. The viewing area has been expanded to 30 degrees, although mariners will still have to align the two lights on approach to the Ash Creek Channel.
The lights are maintenance free for the next 5 - 7 years at which time they only need the battery replaced. The lights are timed together using a satellite signal, so they will never be out of sync.
The flash rate was altered slightly to a 6 second flash at the rear and a 3 second flash at the front. This means the two flashes are in sync every other flash.
This change has been registered with the USCG and will appear on the light list for Long Island Sound.
