Modern Headlights
The H6024 is a sealed beam, not a 2 piece item; just look it up. Any chance the auto store messed up the parts in the boxes?? Check the PN again.....
If you do indeed have a 2 piece light, then random changing of the bulbs is not necessarily going to work. The center of the light has to be at the right point, and any reflectors or blockers need to be at exactly the right locations. So no way anyone can help you if the lights are no ID'd correctly, and probably not even then.
In what way are they awful? Too dim? Light not going in the right directions?
