Well, you would think that a light that says "super bright" would actually be super bright. Not the case with these bulbs. My stock bulbs were brighter than the Sylvania Zevo bulbs. For the price I expected a lot better than stock. Not quite sure why on the the back of the package it says "for off-road use only." They didn't really qualify for on-road use. I have tinted windows and had to roll them down to see when backing up. Never had to do that with stock bulbs. Long story short, if you're buying for quality and longevity, Sylvania makes some great bulbs, but these are a disappointment. Save your money and stick with their other bulbs.
