My buddy ran the fancy real ones and he had to do all the same stuff.
As for quality... This actually gets into my personal life if you can believe that.... For some reason every 510 I've had in the last 5 years I been unlucky and had something smash out the headlight on the drivers side. A mud flap twice and big rocks a few times haha

Once was on the way to Shasta, Lucky for me James sold me a new one for a dollar

Only in my 510's too!! The BMW light faired the best out of the sealed beam units by far!!! It only has 1 crack, it's from top to bottom though, which sucks but doesn't seem to affect the light diffusion. The only thing I would do is be more careful cutting the plasic on the light, it's kinda thin and easy to go through. The lights work awesome compared to H4's 5x better!!! I wonder how nice they would be with HID's

I liked Hainz better...... Can we trade back?
