Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I installed these on my 100 series Landcruiser and they fit perfectly in the housing. Wouldn't say they are much brighter than the previous halogen bulbs however they are much nicer with the colour of light being super white/ blue. The beam pattern is also good and does not shine into oncoming drivers eyes. For the price I cannot fault them.
