When our kids were little, I used to drive an old Rover 2600 that had a low-oil warning light on the dashboard. This thing was huge for what it was, about the size of an adult man's thumb nail. The electrics in that old car were pretty bad, and this light stayed half-on all the time in a soft ruddy glow.
We were all returning home one evening and this glow was just becoming visible in the gathering gloom, and one of the kids asked what it was.
Of course, we told them it was the Sunset Meter that told us it was getting dark enough to put the main lights on...
