Honestly I don't write too many reviews on things I purchase and I am thrilled with these headlights.Build Quality: Built just as well as the stock headlights, a strong plastic case, clear beautiful lenses, and the halos are lit all the way around and shine rather bright. The included wiring for the halo rings is also very sturdy, pre stripped for easy splicing, and the included step down box for the rings comes with 3M double sided tape already attached.Brightness: Out of the box the bulbs are extremely bright. It is a different type of bulb than the stock Sonic headlights I believe H1 and H7 are in this, but that is pretty common with projector headlights as they concentrate more. Much brighter headlights than the stock ones I upgraded from.Packaging: The packaging was very nice, came encased in a shrink wrapped Styrofoam that doesn't bust into a million little pieces when you open it. They were well protected, and no damage was noted to the headlights when they arrived.What could be better: The only thing I can see that could be better, is that on the stock headlights the alignment screws are easily accessed from the top with a Phillips screwdriver, on these you have to access it either with a snub-nose Phillips screw driver or a wrench, but the headlights I received required no alignment whatsoever and were good to go without it. But it would be a slight pain if they needed aligned, however this is really nitpicking to find something wrong.So in summary if you are looking for some great headlights you can't go wrong with these, they are bright, sexy ,and a perfect fit. I hope this clears up a few things you are worried about looking for headlights.
