I've only had it for a few days, but it works good.  So I ordered 2 more.  I haven't installed it in a vehicle yet, but on the 12v power supply with a wireless camera receiver plugged in it looks pretty good, maybe a little grainy, but plenty bright.  Not sure what the teal wire is for, because there really isn't any directions.  But it works, it's cheap, and what I wanted.  The wires aren't really long, but really happy with them.
