Morimoto HID bulbs, for non-premium lights?

Hey all. Was looking at lights yesterday and noticed on morimoto when you search by vehicle, it brings these up. Are these for use with the non premium reflectors? I would assume so as the premiums are fully integrated lights correct?

the 22+ tundras all have LED headlamps, they are not serviceable, the only replaceable bulb on the headlight is the turn signal in the base headlamp, not the upgraded headlamps, they have an led turn signal
if you want different headlamps on your truck, you will need to purchase from aftermarket, there are plenty of threads here that go over some that have been installed.
some brands i have seen in threads are Anzo and Alpharex, and they are $$$$

 

Fascinating, thought for sure the base lamps were just standard reflectors with led bulbs. Appreciate the response
