Having trouble getting the light to function as advertised. I installed a switch back led turn signal and can't get the white lights to turn off when the turn signal is activated. I have the led relay installed also. So to trouble shoot I reinstalled the factory relay and the led's are still doing the same thing. The white ( or running light) won't turn off when the amber light is flashing. It does it with the led and factory relay installed.They do not hyperflash with the LED relay in. I'm unsure if it's a relay issue or a bulb issue, it is a dual function bulb. any ideas? Do I need to wire in a resistor even though I have the LED relay? Thanks!
