Wagner BriteLite halogen capsule bulbs are designed to provide enhanced visibility through brighter, whiter light and a longer beam pattern compared to standard halogen bulbs. They use a combination of Xenon gas and a high-powered filament to achieve this, resulting in up to 80 percent more light and a beam that extends up to 120 ft. further than regular halogen bulbs. These bulbs are suitable for various automotive applications like headlights, fog lights, and daytime running lights, and they comply with DOT/SAE standards. Order the style recommended for your vehicle/position.
