they look cool... would be better if the whole thing was smoked. i didnt read the page... i wonder if they have resistors and such to give them the proper wattage/voltage/whatever.... I really have no idea what you need to do to hook up LED's... all i know is that they take a different ammount of current to run them than the regular bulbs.
You're better off going with a bulb conversion using the factory housings. The stock reflectors give better light throw than the handful of directional LEDs on the aftermarket units. The stop lamps (3157) are a straight-over plug-and-play switch out. The turn signal (3165) requires a resistor wired in parallel to mimic the load of an incandescent bulb so the flasher doesn't strobe.
