I run HID headlights on my cruiser, and am thinking about led indicators. One thing that has always bothered me is having to use load resistors to get hi/low to work or indicators to flash at the right rate.
Why does the circuit need this extra resistance? All it is doing is turning power into heat. Is it due to the resistance of the switch/relays not being truly infinite so enough current flows to trigger?
I've looked through the circuit diagrams, and tried searching but haven't found out the 'nuts and bolts' of why, just suggestions to fit load resistors to achieve the original load on the system. Is it a specific component that causes this behaviour?
Anyone know the electrical theory??
