little red light

As I was at the CAO, trying to get into the observatory or the garage, often at night, I realised that I needed some sort of light (red, ideally) so I could identify keys in the dark.

Once home, I located a little red LED squeeze light in astronomy box α. It used to hang off the telescope trunk latch. Wasn't currently using it for anything. I put it on the CAO key chain. More precisely, I put it on the quick release on the key chain.

It was good to repurpose it.
