Ok, so not really a Focus problem, but still Ford and lighting.
My dad just bought a bunch of LED bulbs for his '08 F-150. He bought lights for the front turn signal bulbs. They look pretty awesome with running lights, and four ways, but they hyperblink with the turn signals.
I know I need resistors, but what kind? What ohm/wattage? Also, where do I put the resistor? Anywhere in between the bulb/plug, and the power source, right? There are two wires going into the plug..I'm assuming one is power, and one is ground, and the resistor would go in the power/red wire.
