Electronic Circuits - 12V LED Battery Level Indicator With Zener Diodes & Resistors

This electronics video tutorial explains how to build a 12V LED battery level indicator using zener diodes and resistors. It also explains how to determine which LEDs will be on and which ones will be off by comparing the voltage of the battery with the total voltage drops across the light emitting diodes and the zener diodes.
