I read through as many threads as I could find about this. With LED bulbs in the tail lights, if my brake lights flicker when in park or pressing the brake, I need to add a resistor. If my turn signals blink fast, I need to add a resistor.

Does this mean at the back I would need like 8 resistors if I switch to LED bulbs on stock housing? 4 on each side?

What is the difference between using resistors and turning off cold monitoring?
