The clock in my dashboard doesn't have a light in it, so I can't see the time when it's dark. This bugged me so much, I made a replacement clock (3d Printed, Arduino driven LCD) . Oh, and I stuck some USB ports in there as well (they kick out a total of 3Amps, so enough to charge a new fangled smart phone).
It's a bit rough & ready, but at least I'll be able to see what time it is now.
