If you go by the letter of the law (your legal residence is another state) then you should apply it uniformly (your vehicle's tint is illegal where you currently are). You can't pick and choose which technicalities apply to you.

If you go by the spirit of the law, then a grace period would be reasonable to apply to infrequent visitors. However, you travel there daily, so that does not apply to you.

Doesn’t really seem like you have a leg to stand on here.
