TL; DR: 50% failure in the first 6 months and not much brighter than standard bulbs. On my 2008 Toyota Tacoma, after almost 10 years (I drive with low beams on), I had the original headlight fail. I bought these two packs and replaced a burned out lightbulb. It was no brighter than the remaining factory bulb. The remaining original factory bulb lasted until November 2020 before blowing out. I replaced it with the second bulb from this pack and this bulb blew out today (March 28, 2021) after less than 6 months of use. The installation is the same as for the factory lamps.
