1500 part needed

I am looking to see if I can
beg, or purchase a rear
license plate mount that still
has the plate lamps on it. I
have a twin jet ski trailer,
and I need to illuminate the
plate. The trailer sits so
low, I can't mount the plate
below the tail lamp, and I
can't find a lamp with the
clear lens on the side. I
figure if I use the 1500 plate
mount, I will mount it on the
rear rail, and that should
solve the problem.

TIA,
Brad
