OSRAM LEDriving headlight bulbs are the best retrofit bulb you can get.
They are completely solid state, have no cooling fan. and can be put in sealed enclosures without burning up.
They correctly illuminate stock housings, as long as you orient the throw correctly to fill the stock housing.
I've got them on my 2001 Suburban with Retrofit projector housings, and my 2016 Fiesta ST with stock housings.
