There are several issues with the glut of LEDs available on Amazon at present.
While an LED unit can get close to a halogen in terms of usability in a reflector designed for the latter, it’ll still end up with glare to some extent. I had a decent set of H7s in mine with low glare.
The main issues I’m seeing now are LED cluster size versus halogen filament, placement versus halogen filament, adaptability (some have easily movable adapter rings that hinder correct orientation. Bar-none the major shortcoming is the lack of thermal management. Majority I saw on Amazon (cursory look) had no means to dissipate heat. Those with fans can be hit or miss on fitment into the low-beam due to clearance with the back cover. I had flexible copper mesh and it worked well enough though after time the units did dim somewhat compared to startup.
If I were doing this again I’d try the units from Philips, Sylvania/Osram, or genuine Porsche.
