no. not if you buy them from superbrightleds.com because those bulbs have the resistors inside of them. now if you were going to buy a box of single leds and find places to put them in your truck, you would need to wire a resistor to each individual led that you used.
also you would need an additional load resistor for your blinkers if you replaced them with leds, because your truck might give you a hyperflash/bulb out signal.
