However, if you have a late model Ford Explorer (we have a 2017) and find the backup lights far too dim, these will only help marginally. Light is definitely brighter and whiter than factory but we found it still wasn't enough. That being said I doubt there are any that will be brighter than these so we'll stick with them. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Good output, easy install *by D***0 on Reviewed in the United States on January 24, 2019* They were very easy to install in a 2009 Honda Civic, bulbs fit good and are much brighter than the stock halogen bulbs. They are a little blue, wish they were a little more bright white but they still do the job and light up what is behind the car. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect fit on 2014 Dodge Dart GT *by A***R on Reviewed in the United States on November 7, 2018* Perfect fit and very bright.
