OSRAM Ultra Life car lamps are almost unbeatable when it comes to durability. They have a four times longer service life than conventional standard halogen lamps and last up to 100,000 km (with an average annual mileage of 14,259 km, of which 60% with the light switched on). Osram offers a 4-year warranty for its reliable Ultra Life headlight bulbs (fourth year when registering online at www.osram.de/am-garantie). In addition to these advantages, the Ultra Life headlight bulbs impress with their modern design with silver dome (H4/H7/H11). They are therefore the ideal choice for frequent drivers or daytime running light users and are also suitable for clear glass headlights.
