Built with a reinforced filament and a proprietary gas fill, they are designed to produce a brighter, whiter beam pattern that helps you see farther along the road while maintaining a controlled cutoff to minimize glare for oncoming drivers. Because headlight output diminishes with use, the bulbs are sold in pairs to restore balanced illumination across both sides of the vehicle.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these bulbs improve visibility on the road?\u003c\/h3\u003e\n\u003cp\u003eThe XtraVision design focuses light farther down the road so you can spot obstacles and signage earlier.
