They're "Ok". As many other places/people have said, they need to be 'sealed' with 'flow-able silicone' as soon as possible or else moisture gets inside.Good - Look awesome, lots of lights, comes with a separate 'DRL' LED bar which is SUPER bright. Comes with its own halogen bulbs pre-installed, including turn signals. Bolts in fairly easy.Bad - Needs 're-sealed' before letting them sit out in the rain. The halos are HORRIBLE... WORST halos I've EVER seen on any car... They appear to just be lit by two tiny, underpowered LEDs somewhere near the bottom.. Which means the full halo DOESN'T get lit up, so its more of just a 'droopy eye' that can BARELY be seen during the night... Daytime? Don't make me laugh... You wouldn't even know they are on.They don't quite fit HIDs, which is most likely the #1 reason why anyone wants to buy them anyway. The grommets are too shallow to hold all the HIDs wiring in, so it ends up bulging out and looking awkward on the inside. The light beams can't be adjusted without removing the ENTIRE headlight assembly from the car, which makes adjusting them at all almost impossible unless you have the world's smallest hands.The little 'bar' that runs along the top of the headlight, does NOTHING. You'd think it would light up or something to be like an eyelash, but it doesn't do anything. Just sits there looking useless. I've seen some people mod the assembly and put LEDs at the ends so it lights up though, which does make it look really good. When its cold/hot outside, the plastic mount points warp pretty significantly. This winter was crazy for them it seems... I'd get up to go to work in the morning, and find that my left headlight was pointing a good 3 feet lower than the right. After the car warmed up and I've been driving for about 15 minutes, the heat finally reaches the housing and it 'fixes' itself, lining back up with the right light. But then once you've been driving for 40min-1hr, both headlights seem to point farther up (left going up about a foot while the right would go 2-3 feet)... So maintaining an accurate light position may be something unobtainable. Might try finding some sort of rubber washers or something to put under them to see if that'd absorb any unwanted 'movement'.Other - It has reflectors on the very edge of assembly. The only other headlight assembly I've found that'll fit the same vehicle as this does, moves the reflector along the inside so that the turn signal/parking lights actually are reflected outwards for cars next to you to see. Granted, these reflectors seem to have a TINY little bulb hidden behind them, but they don't appear to do anything. I've turned the parking lights/signals on multiple times, both day and night, and never see any sort of light from them. Figuring they just blown bulbs (on both assemblies), I removed them to see if they were actually working... which they were, but I guess they just aren't meant to be seen from the outside... kind of a pointless venture if you ask me.The website from the manufacturer says that 'every bulb is replaceable'... but I seriously fail to see how that is so. It seems as if the halo's LEDs are inside the assembly itself, meaning you would have to remove the clear outer shell, figure out how to remove the halo, then figure out how to take the LEDs out. Once I figure this out, I plan on finding much much MUUUUUCH brighter bulbs to put into them...Anyway - While I've pretty much ranted and bashed on the headlight assembly, I'm still giving it a 4 out of 5. This is because that while there is significant effort required to get them installed/working somewhat decently, they do look pretty freaking awesome on the car, and that's pretty much why anyone would be buying them: because they look cool, and because they want HIDs that are street legal in many states.
