You will have to align the lights. Just as with OEM headlights, that you need to adjust the beam. I tried what stryker said, about just loosening the bumper enough to get to the other bolts, but it was just easier to finish loosening the thing and throw it to the side. The light output is pretty good, if you get some good bulbs in there. Right now my budget is on my suspension, so the 40 bucks a pair for the bulbs will have to wait a little longer. If you are good with wiring, you can also invert the outside parking light, with the bumper turn signal. That way the bumper turn signals come on as parking lights, and the outside parking lights on the headlights, only turn on with the turn signal. There are DIY on how to get that done. I want to do it on mine, but for now, the outside light just has a blue bulb in it that never turns on. Are you comfortable with taking off your bumper? A body shop will charge about 1.5 hours of labor I think to do it for you. But you would still have to seal the headlights yourself before taking it to them, and hope that they will be flexable with you as to how you want to have the wiring.
