1) How common were cars with automatic gearboxes in the US in 1953? And in 1961?

2) I think we need a new wireless router. Any points I need to consider? Any recommendations? Any anti-recommendations?

I would like a very small light, to place inside a translucent bowl, and so light it up from the inside. The bowl is approx 1.5" tall by 2.5" wide at the top. There is no mains power accessible where it currently is, so I would prefer something battery powered if possible.

How should I do this?
