I swapped out the parking lights in the stang with led 3157 / 3057 xenon lights. They work just fine when I turn my parking lights on but the turn signals wont blink. It also makes a whining up noise and stops shortly after when i turn the key to accessory. Has anyone done this before? Whats the problem? Can this be done? Thanks for the help

 

IF you look right next to where you bought those overpriced led lights you will see a high wattage load balancing resistor that you have to wire in. The flasher uses the resistance of the bulbs to know when they are burned out and to tell you by not flashing. Leds do not have the same resistance as the bulbs so the flasher things they are blown. Installation is as simple as cutting one of the wires(either pos or neg) that goes to the light and then putting the resistor in. Its non-polarized which means you can't hook it up backwards.

 

yup, as ttocs said, you need resisters on both parking lights, been there, done that.
