I recently purchased a truck that has these headlight assemblies in it, and wanted to leave a quick review for anyone looking to get a set.
First off, these assemblies look really good. The halo's are bight and the triple LED under each low beam look good at night. They fit well (I've had mine out several times to aim them). The high beams work well, and project a good amount of light, however, my experience has been that the low beams are 'focused' very poorly, and even after upgrading the H1 bulb to a better (and slightly brighter) unit, light output is still unacceptable for night driving. Aiming the lights differently helped slightly, but again, the light output on low beam is very poor. If my truck didn't have fog lamps to supplement the low beams, I would never consider driving at night with these.
While probably not a 'malfunction' so-to speak, I've also found that the halo's tend to not light up in cold weather (20° and below). Once the ambient temps come up though, they work just fine...
Again, while good looking, be wary of these if you intend on doing a lot of night driving where you need to use the low beams. You'll be left wanting something that provides more light output.
