If you go with the LED bulbs, don't forget the Load Equalizer. You will need it for the flashers to function correctly since the LEDs draw so much less current than incandescent bulbs. Some LED units have the equalizers built in. If not, you can find them in any of the major catalogs where they plug into the main harness for the front and rear turnsignals.
