#180: All-weather sunroof

For those of us who live in Northern climes, a car sunroof tends to stay sealed closed for half the year. This a particular problem for anyone who suffers from seasonal affective disorder and who has to spend long periods in a vehicle (away from a conventional, room-based lamp).

Today’s invention is a daylight spectrum lamp fitted in a vehicle to give the impression, and emotional benefits, of glorious daylight streaming in from above (even when the roof is firmly shut against the dark Winter elements).
