Unless you have projector (ellipsoid) style headlights, they are a waste of money. Not to mention they blind oncoming traffic with uncontrolled beam scatter. O.E. LED headlights on newer cars are designed to put the light where it should be, older halogen based lights are not.
That’s a concern. From things I’ve been told, it sounded like it’s not an issue with newer bulbs.
This is for my ‘11 f250. Got one burned out and thought it a good time to upgrade. Don’t want to mess with changing housings.
