Excellent pair of fog lghts with super bright and wide angle light focus making it perfect for vehicles. Installation is very simple by simply connecting to a power supply ranging from 9V up to 32V. Of course the higher the voltage, the brighter you make it. It nicely come with mounting accesories and screws however the only down side is that it does not come with any instruction manuals which is a very basic but, important piece of paper. Other than that this is perfect.
