just use any old rectifier diode. 400x. x being any number. Theres a white stripe on one side of the diodes. Those will be the sides that join together and go to one side of the LED.
Reido113......did you check to see that the turn signals themselves are working correctly? i suspected the diodes wouldn't be needed since the bulbs aren't polarized. but i did it anyways since i'd already cut the wires when i realized that.
