I want to use that flashlight, and mod it to a different colour led but I need to know if the pbc board has polarity.

So there is polarity like + and - on the board O_o?

patience grasshopper. And yes, leds are polarized, thus, 99% of the time their driver boards are polarized.

Post a comment on that Instructable, I'd expect the author to answer it. L
