A majority of reviews on Amazon.com indicate Sylvania automotive bulbs rate highly when compared to other brands in terms of performance. The Sylvania 9006 silverstar high performance halogen headlamp is noted to increase visibility by 40 to 50 percent and create 10 percent wider visibility.
The bulbs are also noted for being easy to install and come with a one-year warranty. A common complaint from Amazon.com reviewers is that the bulb's lifespan is too short. Several reviewers attributed this to the increased brightness. It is also noted that the Sylvania 9006 silverstar high performance halogen headlamp is not recommended for Honda, BMW and many foreign brands, because they run up to 15 volts to the headlamps, causing the bulbs to burn out even faster.
