Hello,
I thought I'd share my latest dome light solution for the rear seats in my Mirage.
I've used strong magnets to attach a headlight onto the central roof pillar. These magnets have a nominal pull force of 30.5 lb and are just strong enough to hold the weight of the flashlight and resist wobbling around in speed bumps. It would also work to not screw the light on the flashlight and just lock it onto the magnet itself (the magnet snaps to alkaline batteries), but then I would lose the possibility to change the tilt of the flashlight. This contraption allows to rotate and tilt the light freely around.
Points for improvement:
-the felt fabric in the roof increases the distance between the roof metal and a magnet, which is why an even stronger magnet would be favorable to also allow hanging it at other locations. With the current magnet, I can only hang it onto the central pillar or onto the exposed metal parts in the trunk or around the windows.
-it can be used to hang other stuff in a Mirage. My next project is to hang my GPS onto the dash with some magnets as well (bought too many of these)
Here are some photos:
