I bought these for my tractor to put in the rear to see clearly at Night while plowing and to use as strobes when plowing up near the road for safety. They have many functional, full white,full amber, full white+amber, white strobe, amber strobe and alternating white to amber strobe with an easy to mount and use small controller and very simple wiring with a built in relay and fuse. They are quite bright in any mode and nobody will not see you when there on. Only thing I feel could be changed is if they had a double mount. They have a single center mount which would be fine for most applications but the option for a double mount would make them stronger "although with a center mount I can slightly turn them if I wanted them pointed at an angle outward" if you were bolting them to a metal bumper or front brush guard they will be just fine. I'll see over the winter how they hold up in the extreme cold and the shaking and harsh movements and vibrations that come along with snow plowing.
