Review on 🚛 8pc 2.5-Inch Amber and Red Round LED Trailer Clearance Marker Lights - DOT Approved with Reflector Lens, Grommet, Flush-Mount, Waterproof IP67 - Marker Lights for Truck Trailers by Black Croom

Mounted on an Omaha standard stand. The bushings were tricky to attach (I think that's a good thing) and I'm sure they and the lights they hold are secure. The headlights look great and the reflector works well. As long as the headlights work, this remains a five-star rating. I bought these headlights to make side markers and another brand for 4 inch round rear wheels. I ended up returning another brand's round 4 inch headlights and bought these brands after seeing the difference in quality side by side. These lights fit snugly into a well-made socket, have appropriately sized copper wires and dielectric grease preinstalled on terminals that fit snugly into the lights. The other brand had thin aluminum wires, no dielectric grease, the connector barely stuck to the flashlight with any holding power (I planned on gluing it) and went freely into the sleeve, which I could easily push the flashlight out of with a finger (I thought also remember to glue them). I recommend paying a little more and getting these lights for the reasons above.
