Retrofit apron lighting and retro-reflectors in Scorpio MK1?

Hello! I found a Tread from 2009, but it was about an MKII. I have a MK I GL from 1990. On different pictures in the net I saw that this model also had the combined apron and retro-reflector lighting in the doors (so that the cyclist sees where he is banging against :-)). Since I have another set of these lights in the fundus and in the doors of my car are suitable openings with rubber caps, now my question(s): Is the installation of these lights at least prepared at the front of the scorpios, is it worth disassembly of the door? At the back I had the interior cladding off due to another construction site, since now no plug has jumped into my eye. Thanks and nice Sunday still, Johnny
