My side markers don't have any resistors/diodes
-off when lights are off
-dim when parking light is on
-bright blink goes opposite of factory blinkers
how many wires come off the side markers? The audi markers only have two wires, a power and ground. so to make them work as parking and blinkers they need the resister to make them dim for running lights and then the diode prevents the power from the runing light to back feed the turn signal. So when the turn signal is active it will blink full bright.
