I love these headlights.I had a pair of burnt out smoked headlights, so this improved a lot to the look of my car. And for the halo rings you don't have to do any wiring, actually there are no wires you can access from outside the headlight, so that was a big deal for me, because my former headlights had wires uncovered and that led to damage on a couple of them.Pros:-Bulbs are adjustable (I guess replaceable too)-No extra wiring needed for halo rings-Very good visibility even with low bulbCons:-Halo is not visible during the day because is not super bright (altough I actually like that because the normal look is awesome)-Fitment was a little bit tricky but once on position they fit excellent
