I do have a taillight with integrated license plate holder but the Bargman LED Recessed Double Tail Light part # 47-84-527 would not allow for this. Instead, you would want to use the ONE LED RV Tail Light part # RVSTLB0061 which does have an integrated license plate holder.
If you would like to use the Bargman LED Recessed Double Tail Light then you would want to also use the LED Trailer License-Plate Light w/ Mounting Bracket part # LPL55CB as this could be mounted in any visible location... view full answer...
