Two of these good pieces I have on my Toyota Land Cruiser 100 at the "Bull Catcher". The high-beam road illumination very good, and with the LED rings can also be sure that the large ship is seen. ;) The installation is not quite trivial, but everything necessary is included (cable, mounting hardware). The spotlights are stable and difficult, so you should ensure a proper fastening. The best make a workshop, but the experienced layman should manage it well. The installation took me only about 30 minutes, however, I had already pre-made holes at the "Bull Catcher".
