Dome light fitment in any way?

Hi guys,

So we FINALLY got the Roomster home on Friday, and got to take it into the city a couple of times.

Overall pretty happy, but we must also admit there are some functionalities we are missing from the Octy 3. Oh well...

One of the things that are not only missing, but also proven slightly annoying, is the lack of dome light for the rear seats.

You may wonder why this is, but we are using this car for getting our kids around. And when you do that, you tend to want to see them in the mirror as you're driving, stand there fettling with a stupid childrens seat belt buckle, and so on... Having a dome light there, connected to the dome light up front would be great (door triggered both front and rear, with individual "always on").

Has anyone done this before? There is the spacing in the profile of the roofliner maybe?
