Thank you! 
The small blue light is supposed to be attached to a block.

It is not possible to glue the block to the vehicle unless you skip the block with the orange lights. On the real engine the blue light sits on a flat red square with another white light below. That red square is located directly above the block with the orange lights. So I cut out a 1x1cm red square from one of the misprints and laminated it to 1mm card.

This was laminated to some leftover white paper and painted black.

A smaller rectangle cut from white paper was glued on top of the black side.

The light was glued to the red side.

Then the plate was mounted on top of the block at the rear of the vehicle:


The side mirrors needed to shine. I cut the parts out and laminated the black half to some reflective card from a chocolate box.



I cut off the black handles from the kit parts and laminated them to the reflective side of the mirrors.


The drawn mirrors were discarded.
When I was looking at the finished pieces I noticed that they were identical! Volker forgot to mirror the mirror parts. To fix this I cut off a small amount of the handles of both pieces.
The unused part for the small blue light box was recycled to make two top side mirrors:


Volker's kit does not include these but they are present on the real vehicle.
