helicopter accompanied by two small lights

at 6 pm, i heard 2 very loud helicopters fly over headed sse. which was unusual in itself, i've lived here more than 20 years and am familiar with the flight patterns of commercial jets and the small aircraft from the nearby town airport. i live in a very rural area with no military bases close by. at 8:40 pm i again heard the sound approaching from the sse this time and went outside to see a large helicopter being accompanied by 2 small lights, 1 in front roughly 100 ft. and the other in back and to the side. i've never seen anything like it. i was in the Navy in a P-3 squadron and have seen many types of aircraft.
