I just finished changing all the interior light bulbs to LEDs bought from AUXITO..These things are much much brighter than the stock halogen. I installed them on license plate, dome light, map light, trunk light, and parking lights. In other words I replaced all of the W5W bulbs. I am overly impressed by these. Just pull the old bulb out and plug this one in. Nice and snug fit. Only been a couple of days so can't comment on longevity. No flickering anywhere.
