Using Sylvania's Tri-Band technology and tuned filament, the bulbs produce a whiter light that helps make road signs, lane markers and potential hazards easier to see. Sold as a pair, these bulbs are designed to replace both headlamps at once for consistent color and output across both sides.\u003c\/p\u003e\n\n\u003ch3\u003eHow much brighter and whiter will my headlights be?\u003c\/h3\u003e\n\n\u003cp\u003eCompared with many standard OE halogen bulbs, the SilverStar Ultra aims for a noticeably whiter color temperature and improved perceived brightness, which enhances contrast on the road.
