Dim, yellow, _flickering_ light. ;-)
Sometime in the late 1960s or early 1970s, my dad made a "light
dimmer" that was just a metal project box, a diode (half-wave
rectifier) and a toggle switch. Flip the switch for full brightness,
flip again for "dim". It worked fine, for what it was, but the dim
light wasn't that good to read by.

Then there were the "bulb
savers"--small discs probably containing
nothing more than a carbon resistor
I've seen products that match this description (in the US) that
contain a diode, which gets placed in series with the bulb. They
work great if you like dim yellow light.
