Go back and reread the light test or rewatch whatever YouTube video you saw.
1) The test doesn’t apply to 1959 Topps, which is known to have used thinner card stock.
2) It might not apply to other years, depending on where card stock was sourced.
3) It might only work for phone lights, because they put out less lumens than actual LED flashlights.
If you look at how strong the light shines through the 1959 compared to the two others, it’s certainly possible that your lightsource is simply too strong for the test.
Beyond that, I’m sure Andy Broome taught his team to use methods beyond the light test, since he was one of the first to publicly talk about the test, itself.
