What is the maximum tint allowed on a car or a SUV in Tijuana, Mexico?

I’m reading some conflicting information, e.g. https://redd.it/92grg1:

There’s a certain amount of it allowed, not really sure about the gauge (or whatever the measure is), but there is a lot of places in Calle 2da between Negrete and Ocampo, just ask for what is "okay".

All tint outside of factory tint (which is very light) is illegal in Tijuana and has been since 2008. The law is randomly enforced though, as it seems to be with most traffic/vehicle laws in TJ.

It is in fact illegal to have your windows tinted if they are dark enough that you can’t see inside of the vehicle.
