2021 f150 XLT 302A 4x4 3.5 eco.....replaced my front turn signal bulbs from halogen to led, Also, have the zflash strobe system for work. With the strobe system off....as soon as I tried the left front trun signal, no flash, got my son to change the settings in forscan for it, no it just flashes dimly, exchanged led bulbs with the right side, which is working perfectly, same issue....tried a resistor, which I shouldn't need, still the same. I'm lost.....
