A backlighted trailer step to facilitate a trailer users getting up onto a trailer for more convenient access to a load being carried, and which includes a backlighted cutout portion of the step for displaying indicia such as the trademark of the trailer. The lamps backlighting the indicia also provide a visual locator for the step in the dark, and function as a utility lamp to provide light for such things as servicing the trailer or changing tires at night, and increases safety by improving the visibility of the trailer to traffic approaching from the side.
