I have them and I really like them. They are LED so you will need a load equalizer but they come with the equalizer and it's really easy to put in. The adaptors I have are the ones from newspeedmaster.com. If you don't want your mirrors to vibrate, don't get these, the mirrors I mean, not the adaptors. I think the vibration is managable. It only really happens durring acceleration, when at a constsnt speed they are fine.

Hope this helps

Let my dying thought be that every mile was fun and let my tombstone read,"They never made one fast enough for me."
