Marker light location on Benroy

I'm looking at where I want the side marker lights on our build:

I think the front marker light on the lower right makes sense, but for the rear side light, the spare tire would block a light that low:

The obvious solution is to mount the light above the spare. However, I have foam in the walls and the screws holding the light wouldn't get a good bite (at least with this style and size of light, which I like otherwise because it has a reflective surface and two LEDs, as well as easy mounting.) So I'm thinking about mounting it as shown (it's masking taped on in the picture), or perhaps a few inches lower, but at least above the tire holder and on the line with the galley bulkhead. That has an added advantage that I can run the wires in the back of the clothing cabinet, where they won't show.
So the first question--in your opinions, is that back far enough? The rules seem vague on this point. (They say "as far back as possible" or "practicable" depending on which web site one looks at. These would still be back about as far as the edges of the fenders, which is where the back side light often is located.)
Our brake/turn signal/backup lights will be mounted on the hatch, and do not have built in side lights. (Since they will be inboard a few inches side lights there wouldn't be visible to someone forward of the back of the tear anyway.)
I could, however, install a smaller sidelight down low on the side of the hatch. It would still be blocked by the spare tire on this side, but with two rear lights, someone would see the one up high before they came around and then would see the one on the hatch before they clipped us (we would hope). but if I put three marker lights on the side with an amber one in front, and red one in the back on the side of the hatch, should the one "on high" be red, or amber?
Thoughts and opinions?
Thanks!
