Our LED warning lights for EarthX aircraft batteries come with long tails and a metal mounting bezel for the panel mount red LED, plus a male terminal compatible with the EarthX pigtail.

The positive wire from the LED should be connected to the electrical bus (12volt positive), typically to a fuse/breaker downstream of the master switch.  The negative of the LED  should be connected to the fault monitor wire (pigtail wire out the side ) of the battery.

We recommend that the circuit is protected either by an in-line fuse or breaker.

Suggest 7.75mm panel hole.  Wire colour may be white with heat shrink identifiers.
