Flitelite Pilots Green Finger Light.
FLITELite Figer Lights are available in Green, Red and NVIS Friendly Soft White LED's. The lights are easy to use, and include the battery saving 10 Minute Auto-Off Feature. Simply press the swtich on the top of the light with the thumb or against any solid surface in the cockpit - and point!
Attach the finger light with the included Velcro One-Wrap. The wrap is perfect for NOMEX flight gloves, or bare skin. With the flight gloves, the light stays in place.
