Hella and Bosch should both Be OEM..
If you can buy them and return them, I say why not go for the hella's.
My car has some DEPO taiwan ones I got, and they still look great, and they didn't cost me much at all.
When I upgrade to euro headlights, I'll go for either the OEM bosch or hella, or the lightly smoked ones they sell.
