Based on the name, sounds like something that measures light.

If it measures the quantity of light, then I'd say a voltmeter.

If it measures the wavelength/frequency of light, then I'd say it's a wavemeter.

It's something that measures light. Used a lot in photography. Also used in industry.

The industry version just gives a reading in lumens? I believe. The photography version gives an aperture or shutter speed.

It's the time in which light travels a meter(1/c in vacuum)

I suspect each front wheel turns independently, like on very large cranes. Possibly the real wheels do as well. Not sure about the middle axles.
