There's a lot more to it than just slapping a bulb in there. Many manufacturers don't actually make the LED bulbs correctly so that they focus like they should, have the wrong cutoff, or just plain end up not working as well as the *original* halogen bulbs. The replacement needs to have the light emission come from the correct position so that it focuses through the lens or hits the reflectors at the correct angle.
Fortunately, some of us have already done this homework. And for the love of all holy, don't get the damn blue/violet bulbs. Stick to something from 5000˚K through about 6500˚K, maybe 7k at the highest. You also need to make sure it fits the depth and has a driver already included so you can just plug it in to the existing wiring. These are what I have in mine. The H11 are for the Low Beams and Fog Lights. IIRC, the high beams are H7, but also a tighter fit and hard to find LEDs that are shallow enough to fit inside the headlamp assembly; I'd just leave the highs as the OEM bulbs.
When you install them, MAKE SURE the LEDs are laying horizontal, and you didn't twist them 90˚ so they are on the top and bottom. Otherwise, they won't aim right. If you look directly at the lights when on, you can see the shadows to verify they are correct, the light should have a bright "ring" on the left and right side of each lens, kind of like ( ), if the light is not on each side, you probably have them rotated incorrectly.
Lastly, how proficient are you with this kind of job? You do have to remove the front bumper to replace the headlamps. It's not a hard job, but depends on how comfortable you are with this.
I installed these They've been awesome
