they may not have a long lifespan. but they produce more light. the same goes for H7 and H3 that I have tried. I prefer them solely for their performance.

The one bulb broke after approximately 7 hours of use without any intense shaking beforehand.

They fit in a 2020 Hyundai Tucson, on the large scale.
They have a slightly "cooler" shade, not intense.
The intensity is slightly better, be careful, it will not change anything in your beam, whatever shape the mirror gives, it will remain the same. They have a slightly "stronger" intensity, but nothing unrealistic.
I do not regret buying them.
In some older and "tired" lights (bulbs) they may make a more noticeable difference.

P.S. I was hoping to find the Philips x-treme vision but I couldn't find them in HB3 so I ended up with these.

Update: Aug 1, 2024, all good still. Be careful when handling them, do not touch them with "oily" hands. It is preferable with a glove.
