You could do it with two relays and two toggle switches; one switch for the on/off, and one for the low/high beam selection. You may need a little extra fanciness (like a diode or a double pole switch instead of just a single pole switch) if the low beam needs to come on at the same time as the high beam filament, etc.
Those ones on Amazon look like the finest auto parts that China has to offer. Just listen to the person from China who wrote the description. They're not DOT approved, no surprise there. China doesn't care, they just want you to buy their cheap parts.
I looked on RockAuto, and Wagner makes a drop-in LED replacement for your Sami. They cost more than the amazing quality $119.99 specials linked on Amazon, but you'll likely get actual quality for the extra money.
