Seitz Mike Light 3 NVIS Green A LEDs: Hands-Free Military-Spec Flashlight

What microphones and headsets does the Mike Light 3 fit?

Its universal construction is made to fit virtually any aviation headset or helmet microphone, so it works on standard aviation headsets and on flight helmet setups alike. The light mounts to the microphone boom near your mouth, where it can aim illumination at your charts and instruments. If you have an unusual microphone style, confirm fit before ordering.

How do you control the Mike Light, and is it really hands-free?

You operate it with a tongue-activated switch, so you never take your hands off the flight controls or interrupt cockpit tasks. This hands-free control is the core design feature, letting you light a chart or instrument and turn the beam off again without reaching for a separate flashlight during night operations.

What does NVIS Green mean, and why is green good for night flying?

NVIS stands for Night Vision Imaging System. The Mike Light 3 uses night-vision-friendly green LEDs that are compatible with night vision equipment and help preserve your natural dark adaptation. Green light at low output lets you read charts and instruments clearly without the harsh glare that brighter white light can cause in a dark cockpit.

Is the Mike Light 3 compatible with night vision goggles?

Yes. The NVIS Green LEDs are designed for Night Vision Imaging System compatibility, so the light works alongside night vision goggles and devices without overwhelming them. The green wavelength and calibrated low output let you read inside the cockpit while keeping the cabin friendly to night vision gear used in demanding aviation environments.

How many LEDs does the Mike Light 3 have, and what does the 3 mean?

The 3 in the name refers to its three NVIS Green A LEDs. This three-LED array produces the steady green beam used to read charts and instruments. The green A configuration is the night-vision-friendly setup, chosen so the light works alongside night vision gear while preserving your dark adaptation during night flights in the cockpit.

What batteries does the Mike Light 3 use, and are they included?

It runs on two standard AA batteries, which makes power easy to replace and maintain in the field. Plan to confirm whether cells are included before your first flight and keep spares on hand. AA batteries are inexpensive and widely available almost anywhere you fly, so the light stays dependable through long night sessions.

Can I use a 9 volt battery instead of AA cells?

No. The Mike Light 3 is designed to run on two AA batteries, not a 9 volt battery. Using a battery outside the intended type and voltage can harm the unit, so stick with standard AA cells. Keeping the light on its specified AA power protects the LEDs and circuitry during extended night use.

Will the Mike Light 3 interfere with my microphone?

It is designed to mount on the microphone and work alongside it, so your radio and intercom communication stays the focus of the mic while the light handles illumination. The calibrated green beam is aimed at your charts and instruments, helping keep stray light out of your eyes and clear of the cockpit during night flight.

Is the Mike Light 3 military spec, and does it have an NSN?

Yes. It is built to military specifications for durability and reliability and carries the NATO Stock Number NSN 6240-01-362-4902. Its manufacturer part number is ML-8. This rugged, military-spec construction is why it is trusted by commercial aviators, military personnel, and flight instructors for night-flying use in demanding conditions.

What do pilots use the Mike Light 3 for in the cockpit?

Pilots use it for hands-free cockpit lighting during night flights, including reading navigation charts, checking instruments and gauges, and running cockpit procedures or pre-flight inspections. The steady, calibrated green beam gives enough light to read clearly while preserving night vision, so you keep both hands on the controls during critical phases of flight.

Why does the green light seem dim, and can I make it brighter?

The green output is intentionally low to preserve night vision and avoid glare, so it can look dim next to a white flashlight. Fresh AA batteries give the brightest, most consistent green light, so replace cells that are running low. The calibrated brightness is meant for reading charts in darkness, not for general flood lighting.
