High quality replacement Osram Sylvania halogen foglight bulb. Designed for maximum longevity, visibility and performance as a replacement to failed OEM or lesser-quality bulbs. The Sylvania Halogen bulbs are designed to provide crystal clear bright white light. They operate with a higher than normal halogen internal gas pressure and at a higher filament temperature for more light output. The gas pressures help to reduce tungsten evaporation and increase bulb life.
