The light is generated by a small halogen bulb. It has a backup system with another bulb beside it ready to light if the current one burns out. See photo below.

NOAA Nautical Chart 13200

A 'flashing' light is a light in which the total duration of light in a period is shorter than the total duration of darkness and the appearances of light (flashes) are usually of equal duration. So in the 10 second period, the light is on for less than 5 then off for more than 5.

Boston Harbor Light was listed on the National Register of Historic Places on Oct. 15, 1966, reference number 66000133.
