PIAA 15211 H11 Xtreme White Plus

Xtreme White Hybrid bulbs are worth it if you want the lightest possible. They're brighter and provide better contrast versus stock, allowing drivers to see farther with greater safety on dark roads or high traffic areas like city streets at night time - because these lights don't have any filters that would interfere with their visibility! Made from quality materials such as quartz glass alongside our special alloy filaments which reflect heat much more efficiently than common metals do; this means they will last longer without getting too hot and eventually cracking under pressure (which can lead us to an accident).
