You need to buy a additional adapter for it, it's not so difficult to get it, all you need to do is tell the seller which adapter you need for these bulbs. Or you can try some plug-and-play bulbs like I did, which you don't need to buy another aftermarket adapter. My
H7 led headlight bulbs were bought from auxito, they were designed all-in-one mini size, plug-and-play without polarity and any modification, so you can stay away from all kinds of installation problems. And they are brighter, very pleased with the light these bulbs put out.
