Well you used to be able to get dual colour leds that were wired back to

But they would need approx 2V to 3V across them to work. So if you are
considering just wiring them in parallel with the shunt the shunt would
have to drop 2V across it when the equipment takes 2A. When the
equipment takes 20A the volts drop across the same shunt would be 20V,
but long after the equipment stopped working due to a lack of a power
supply from the 12V battery
