Make sure to adjust your headlights after, these have a very hard cut off so they're easy to aim.

One thing though, make sure your lenses are clear before doing this step. I would personally recommend using an off the shelf lens polish kit like Meguiars, but instead of using their protectant coating, I used SprayMax 2k clear coat to seal the lens. If your lenses are faded, the LEDs aren't going to help much, and if anything other drivers will flash you for blinding them.
