Since both a WiFi signal and light are electromagnetic radiation, can I simulate the range of my WiFi Access Point by replacing it with a bright light in a pitch-dark night?

I would probably need to leave all doors open since the WiFi signal has no trouble to shine through them, but it seems that concrete and brick walls are opaque for both WiFi and light.

No. All materials have different absorption and scattering properties of electromagnetic radiation, and these properties are different for different wavelengths of light. Visible light and radio waves will not have the same behavior, especially since houses are such irregular objects made of so many different materials. Furthermore, you wouldn't simulate the correct power or signal-carrying properties of the light either.
