I bought these lights after I got tired of standard halogen bulbs burning out, shattering, or melting wires on the motorcycle I was building. I settled on these specific lights because they feature a combination spot and flood beam setup, meaning that I get visibility at a distance, while still maintaining good peripheral lighting, and visibility of the road immediately in front of me.The lights come in a pack of two, and I was immediately impressed by the quality of the packaging. Both lights came nestled in very thick foam on all sides, and arrived in perfect condition - not always the case with some cheaper brands. The case of each light is dense aluminum, and they have a satisfying weight. The lenses are polycarbonate, and don't rattle or move when the light is shaken. The install for the lights was a breeze - each one has a positive (red) and negative (black) wire protruding from the case, and there are no regulators or reducers necessary. Just attach the wires to your battery, and you're good to go!The mount is a simple stainless steel bracket that uses threads in the case of the light to attach to it on either side. This works well, and despite my motorcycle riding very rough do to minimal suspension, the light has stayed tight. However, as with any steel fastener in an aluminum threaded hole, you must be very careful not to overtighten the bolts to avoid stripping out the aluminum threads. I would have preferred to see a captive nut retained in the aluminum, or clearance for a steel threaded nut on the back of the bolt, to avoid this potential issue.The pictures attached were taken in the daylight, and don't do the brightness of these lights justice, but they are BRIGHT. You cannot look at them directly when they're on, and when in use, they throw a beam of light several hundred feet ahead of my bike.I'm extremely pleased with this purchase, and will be purchasing again in the future, as I intend to add more lighting to this motorcycle.
