I would assume they have something to do with lack of light and/or corking, but somebody asked me about them yesterday and I honestly have never thought about it before.
What exactly are the light spots.

Re: What exactly are the light spots.
Looks like burn marks from hot sun? You can conversely get similar "burning" from cold in winter.

Pictures not the best but looks similar to variegation
15F-110F. 14” annual rainfall. 8b. 3000’

This is my suggestion too.
If your cacti mess in your job just forget about the job.
°C = (°F - 32)/1.8
°C = (°F - 32)/1.8
Re: What exactly are the light spots.
On a fact sheet published by the British Cactus & Succulent Society there are two images, which do not look too different from the one showing on your plant. The diagnosis there is: Mineral- or nutrient deficiency, e.g. Magnesium deficiency. Manganese deficiency also causes yellow spots.
Other causes of lesions could be due to insect feeding, e.g. leaf-footed plant bug of the insect family Coreidae or eriophyid mite feeding damage.
