I found these to be good-quality fog lights. The lens is well-designed, and throws a very wide and thin beam. Beam is adjustable. Metal map housing. Quality stainless steel hardware (both retaining clip and screws). Lamp is made in Taiwan. The plastic material that the clip screws screw into is somewhat too soft - retaining screws can easily strip the material. The electrical connectors are made so the polarity can be reversed - correct polarity must be found by trial and error. This is probably good, in case the wiring on the Freightliner harness was switched around. Connecting backwards at first did not cause any damage, and the lights have worked fine after I got the polarity correct.
