Flitelite Finger Lights are designed to strap on to your finger and provide light wherever your point. Lights are available in Green, White, and an NVIS friendly White.  Lights have a 10 minute, battery saving auto-off. We incorporated this feature to make sure that your batteries last longer, and the light will work when you need it. We designed our finger lights to be economical and effective. 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.  Lights come with batteries included - 3 small button cells.
