I've decided I definitely want to add marker lights for both cosmetic and safety reasons. I don't think the minimum that came on the trailer are necessarily enough (even if I don't get a ticket) and the only limitations I could find were that I probably shouldn't (probably not a ticket if i do but unclear) have the 3 ID lights in the center since I'm under 80 inches. A few extra lights look good but being photophobic I don't want to blind myself in the rearview mirror.
Front & Rear renderings of what I plan to do:
The lights I have in mind are pretty low profile so I'm not sure how visible the ones along the curves will be from the sides but they looked funky when mounted on wall.
I might put a couple more red on the back (I'll have extras and the wire will already be there) but with the long brake lights added on the galley doors I think my visibility will be plenty improved without them.
There will (probably) be a porch light over the side doors but it won't be on going down the road so I haven't bothered to render it these.
