I know the go to is modifying stock housings with Morimoto or equivalent quality projectors but the price of these Amazon knock offs is pretty darn good. It seems like it might be possible to upgrade the likely trash projectors these come with. I don't know if the halo rings are built into the projector or if they rest in front of them separately. Anyone ever open these up and see how things are mounted and how possible it would be to install a better low beam and high beam projector?
