The Sealed, 6-1/2 inch Oval LED Trailer Utility Light, Flange Mount, 10 Super Diode - Clear, item # BUL78CB, does not meet DOT FMVSS 108 requirements, for backup lights so it cannot be sold as a backup light. That does not mean that the light cannot be used in that situation for applications where a DOT requirement does not need to be met.
In short, the Trailer Utility Light, item # BUL78CB, can be used as a backup light, but if your trailer needs to meet DOT requirements you will need to use a light that meets or exceeds those requirements like the 7 inch Round LED Backup Light, item # BUL90CB, which is a surface mount light or the LED Trailer Back Up Light, item # BUL52CB, which is a flush mount light that requires and opening for the light and a rubber grommet, item # A70GB, to mount the light.
