I have recently installed a manual isolation switch in my dash so I can totally isolate the duel battery by switching the solenoid off.
The switch I used has an LED indicator which is very bright even during the day.
Can I install a resistor or something on the earth wire that I have grounded for the switch LED to reduce the voltage flow and therefore the LED brightness?
I would like to about halve the brightness so if a resistor would work what rating should I use?
If a resistor is not an option is there any other simple way to do it?
