Packaging, construction and feel of the bulbs is very good. The overall brightness is good as well, not too bright and blinding for traffic. The bulbs themselves, however, aren't adjustable. I was lucky to still have a good enough beam pattern by not having to keep them in a 3 to 9 o'clock position but most vehicles will require adjustment. Otherwise the pattern and spread is good (i.e does not blind oncoming traffic), not sure about longevity as it's only been a few days but the overall quality is decent. Would recommend.

Awesome upgrade from the original(yellow) to led(white) as a drive to work every night, so far so good,only used it for a couple of days, let's wait and see how long it would last..

Very nice

To me it lookes like a good products. After testing, the beem is good all around. Perfect

It’s no secret the C5 model corvette has terrible factory headlamps. The led lighting has completely transformed this car to modern day lighting, it’s like driving a completely different vehicle at night and immediately much safer to drive.
