In my honest opinion, retrofit is the best way to go. The light output is phenomenal, and done properly does not bother oncoming traffic. Now this process isn't just slap and go, it requires some modifications to your headlight housing. If this is your daily driver, I would suggest getting another set to do a retrofit on. Of course this costs a decent amount, but you will be happy with the results. If you have more questions about this, I know more and more people are doing retros on here.
