So the pear sin really bright, I have only recently found again, as my car was in the shop, and I had a rental car with standard bulbs. What percentage of the accounts, I can not measure it, but subjectively they are much brighter.
I now have the third set in use, the first thought one year, the second seven months. So unfortunately, not particularly durable. This is a problem but I think that all high-performance bulbs. Why only 4 stars.
