I used to work on these in HS-4 in NASNI. The light on the rotors is static buildup. You can see it with the naked eye at night. Darling is right. When the air passes over the skin of the aircraft it can build up to 20,000V on a dry day. As you can see it is pretty dry in the Gulf.
THe lighted tips at the edge of the rotor blads is a ultra low-level light from a spectrum that night vision picks up. This avoids illumination of the aircraft for all to see. Rotor blades in modern military choppers are hard-wired with these lighted tips, activated just before touching down, so that the crew and ground crew wearning night vision goggles can see the actual arc being crated by the blades - a safety visual feature you can see in daylight, but not at night.
This is an SH-60F. Note the exhaust plume (no HIRSS), SONAR dome hole on bottom of cabin, and no mount for the diving board platform for the FLIR. Cool video anyway
nah cant be static, helis have static wicks to discharge static electricity as its a danger to unspent fuel and winching. Plus the friction caused by the sand striking the blades is making heat, which in turn is giving off infra red radiation, making more ambient light for the NV equipment to pick up.
My aviator bud says the flashes is the static electricity builty up, which is why they use a ground when hooking up vehicles for air assault ops. Cool vid.
Sent to us by a naval aviator now stationed at NAS Key West, this video shows an HH-60H landing at night in Kuwait. The lights on the rotor disk are caused by sand striking the blades and causing heat.
it's sand hitting the blades and can be seen at night without NVG's when landing. The hawk kicks up a tremendous amount of dust/dirt.

Evanpilot... you just said exactly what I was going to say.

I have to go with the static electricity build up, but it started to glow as it got near the ground and stopped when it gained altitude
