Review on Partsam Trailer Rectangular Rectangle Running by Roy Boone

There are some differences! Here is a comparison of "Partsam 4X 2.5" Diamond Clear/White LED Bulb 2 with 2 LED Marker Lights for Trailer "Partsam 4X 2.5" Clear/White LED Marker Bulb 2 with LED Marker Lights for Trailer and "Partsam 4X Oval" White Clear Lens 2 LED Trailer Marker Lights Partssam 4X Oval White Clear Lens 2 LED Trailer Marker Lights Only the "Oval” model has slots in the base for cables to exit if you have a flat installation; installing the diamond model was a pain in the butt, but the diamond model has internal surface mount LEDs that offer a wider, slightly cooler white light output that I prefer to the traditional focus dome LEDs in the oval model If you walk to the side, the light of the Oval model narrows a bit. very satisfied; I use them as DRLs (Daytime Running Lights) on two cars, two on each side of the grille and they work as hoped.
