This page refers to features of Anduril 1.

You may be looking for the Anduril 2 manual or Check if you're running Anduril 1 or 2.

When I’m actively using my D4V2 or D4SV2, I’ll keep the flashlight in Off, and the rest of the time I’ll have it in Lockout Mode.

I like to configure the Aux LEDs in Lockout Mode to show me the flashlight’s battery level color with Low brightness.

This serves multiple purposes:

  • I can quickly see the status of the battery
  • Low brightness Aux LEDs indicates to me that I’m in Lockout Mode
  • I can find my flashlight in the dark
  • It looks cool 😎

Battery status colors

When viewing the battery status with the voltage indicator color, we can quickly get an idea of what the state of the battery is by seeing what color the Aux LEDs are showing:

  • 🔵 Blue: good charge (3.9V+)
  • 🟢 Green: medium charge (3.5-3.9V)
  • 🔴 Red: low battery (2.9-3.5V)
  • ⚫️ No color: critical battery (0-2.9V)

For newer versions of Anduril, there are more gradients of colors.
