The large COB style LEDs are a dead giveaway, not to mention the obvious exposed wiring.
As a rule, any good LED headlamp bulb is going to use a quality point-source LED, which is better at providing a focused beam. COBs are too 'spread out' in terms of a light source, and are just about useless at providing the kind of focused lighting that headlamps need.
.. and the fact that the wires are exposed like that just scream "cheap"

Quantity sold has absolutely no bearing on product quality. Lots of terrible products sell incredibly well, but that doesn't make them good. It just means that a lot of customers made bad buying decisions.
Remember the
Power Balance bracelets? They sold REALLY well. Didn't stop the company from having to shell out on a $57,000,000 settlement.
