This is a 95 VT there are two red reflectors as well on the bumper.

Below, this Diablo has the reflector located in the rear bumper.

Note that the Diablo's that are from europe have a left reflector that is white and on the right side it is RED, in the US they are all red.

This is the reflector that came with my kit.

I decided to use the newer style bumper that has the reflector and the backup lights. This meant modifying the existing bumper.

I built metal boxes to enclose the backup lights and the rear reflector light out of 1/8" x 2" flat bar. I welded tabs on the outside of the boxes and countersunk screws to hold the boxes in place. I cut out the openings for the boxes. I used the material from the cutout to fill in the existing light area on the bumper. After connecting the wires I mounted the lights in the bumper and filled in the area with bondo.
